One characteristic of life that is absolutely necessary is water if a human was left without anything except water they will last longer than if they only had food. Another necessary thing is oxygen no one would live past a minute without oxygen. food is another necessary item it will keep you fueled.

life processes that are absolutely necesary for survival are cells, reproduction, and growth and developent. cells are the building blocks of life, and without them we would have no tissues, organ systems, or organs, which are essential to life. reproduction, becuase when one person dies - which they eventually will - another has to take its place in the circle of life. if thi does not happen extinction would be certain, because there would be no new generations. growth and development is also necessary, because if we stay babies forever, we will not be able to fend for ourselves, and we wouldnt be able to live. for these reasons, i think cells, reproduction, and growth and development are essential fators that we need to live.

The 3 characteristics of life that are essential for living things are the cells and its organization, reproduction of each living species and the ability to adapt.
Cells are important for living beings because cells are the basic foundation of anything thats living. Everything in our body or an species is made up of cells. Without cells, we won't be anything and even if we were something without the cells, our body won't function.
Reproduction of each speicies is required because in order for extinction to not occur, living things must make an offspring. If reproduction did not exist, there wouldn't be anything on Earth. Because all the ancestors of the supposedly "new generations" didn't make the "new generations".
Lastly, ability to adapt is important because one must adapt to its environment or its surrounding it order to survive. One might not adapt right away when put in the environment. But as time passes, it must know how to adapt to the unfamiliar surroundings and learn to survive in it.
These 3 are the characteristics of life that I think are crucial for survival.

Their are many characteristics of life that are absolutely necessary for survival. The 3 characteristics i think that are most necessary for survial is that you grow and develop, reproduce, & that you adapt over time. GROWS & DEVELOPS - All living things grow. As they grow, they may change. An example of this is a dog . REPRODUCES - reproduction is when living things make more of their own kind. example --> rabbits . Lastly, ADAPTING OVER TIME - This is the chnage to be able to survive in a certain type of environment. An example of this is a human, getting used/developing the change of being in very cold climates.
The three main things that i think is essetial for survival are cells, reproduction and a persons ability to adapt. Cells are important because, everything in our bodies that help us survive (Like our organs, muscles and bones) are made up of cells. If cells did not exist then neither would these things in our bodies and we would not be able to funtion. The second thing i think is necessary for survival is reproduction because without it, we would become extinct. If we could not reproduce, people will continue to die until there are none of us left. The last thing i found to be imortant was the ability to adapt. I think this is important because, you have to adapt to you surroundings or else you would not survive. For example, if the world suddenly froze, we would probably adapt by growing out all of our hair like animals to keep us warm until we create an entire generation like that. That is why those three things seem to be the most imprtant.

I think that the three most important characteristics of life are...
1) Growth and development because all living organisms need to grow to stay alive. They need to grow because if they don’t they could die. For example if a baby doesn’t developed correctly inside its mother it might have a disease or it might not make it.
2) Reproduces because if all organisms stopped reproducing life on earth would end eventually. Reproduction is when a male and female have intercourse and that is the product. Its like 1+2=3.
3) Adaptation over time is important too because if we did not adapted to cold in the winter and hot in the summer we would die. Like some birds do not adapt to cold and others to warm. It would be like putting a penguin in the desert and a pidgin in Antarctica.
I think those are the three most important because they help us survive.

The 3 characteristics of life that are necessary for survival are reproduction, adaption, and cells.
Reproduction is the process of producing offspring, and it is important to the survival of living things because if living things such as animals and humans dont reproduce then allwould become extinct. there would be nothing here on this earth. living things need to reproduce in order to have the word life.
Adapation is needed because if you move to a new place and you never adjust to your surroundings then life will become hard for you. the same applies for animals because if they dont adapt to their new surrounding then how will they learn how to find food or find shelter, and/or protect themselves when danger comes around? the only way to be stable is to adapt.
cells are also very important because everything inside of us and outside of us is made up of many diffrent cells. cells are the building blocks of life so without them there really isnt no us. cells are put together to make us what we are and to make up or gender, body functions and many more. so without them we are pretty much nothing.
Alyse.G period 2
One characteristic of life that i feel is necessary is "made of one or more cell" i think that its necessary because cells are the building blocks of life and without them, we couldn't live, they make tissues which make up organs and all living things. The second characteristic of life that i feel is necessary is "growth and development". I think that its important because we have to grow and develop or else we would all be babies and we wouldn't be able to reproduce. If we stayed little we wouldn't be able to do as much as we could while we are grown and developed, and if we were babies, we wouldn't be able to survive. lastly i think that "reproduction" is a necessary characteristic because no organism can live forever, reproduction is an essential part of life, we need to carry on the generations by reproducing and making more of your kind of living organisms. I think that to survive and live we need all of these things.

The three things that are needed for survival are water, food, and oxygen. lets start with the water. The reason why we need water is because we need to keep hydrated. our bodies need water to survive. Without it, we would become dehydrated. The next thing that we need is food. Without food, we would starve. our bodies need food to process fat and carbohydrates. without it, we would die in a few days. The last and most important thing is oxygen. We need this because we survive on oxygen. We run just about everything on oxygen. So overall, these are the things that we need to survive.
The things that are absolutulry necessary for a human is food, water and oxgen. Food helps us stay fueled. Water is the most important because we need water to survive and oxygen is imortant and most necessary for us because with out oxyegen we could die.

There are many life processes that are are absolutely necessary for survival. Some life processes that are necessary are; reprotuction, cells and their organization, and the ability to adapt over time.
Reproduction is the process by which organisms make more of their own kind from one generation to the next. If there was no cells reproduction, there would be nothing on earth. We would become extinct if there was no reproduction because everyone would eventually die. Reproduction is necessary because without it we wouldn't exist.
Cells are also very important. Cells are the building blocks of life. Without them we would be nothing and we wouldn't exist.
Finally, the ability to adapt over time is absolutely necessary for survival. This is necessary because we need the ability to change to fit our environment. Things change over time and one day the earth could be extremely cold or extremely hot. We need the ability to adapt to whatever changes are made becasue if we don't, we will die.
Sophia Chronopoulos - Period 4
three necessary characteristics for survival are oxygen, food and water. I say that oxygen is necessary because if we didnt have oxygen, nothing would be living right now. food is also important because this helps us sustain life. everyone needs food. the last characteristic is water. water is really important. its important because like oxygen and food water is something that everyone needs. the only thing is, if you didnt have food you could survive off of water.
-amanda brandell
period 2
One characteristic of life that is absoluty necessary is water because without water, a humans body will dhydrate and the organs would not get the nutrients they need.
Another characteristic that is necessary in life is food because is a human does not have food it will also not get the nutrients the body needs and the body will start to "eat itself". Frist the body will eat the fat that it has stored when you eat, then the body will start to eat away at the nutrients of the humans bones and musceles.
The finnal absolutely necessary for life is oxygen because if the body doesnt have oxygen t5hen the body will not give the musceles in our body they need and the human will die of suffacation.
Ariadne Rodriguez
Period 3
If I were to choose three characteristics of life that are absolutley necessary for survival would be:
1. Oxygen- because without oxygen we would'nt be able to breathe or to live.
2. Food/Water- because without food or water we would starve and or dehydrate and not be healthy and we need food and water to survive and to keep energy in our body flowing.
3. Shelter- because without shelter we wouldnt have a home to stay in or to adapt our surroundings to and we would need clothing and a place to sleep in every day.
I choose these three things becuase without them I wouldnt live my own life good and i wouldnt be healthy. When we live we reproduce and increase our population.

to survive we need cells & their organization, growth and development, and the abiliy to adapt. we NEED cells because they are the building blocks of life, also we need cell orgainzation so that each part of the body has a task to do. we need growth and development because if we stay the same height and weight we are when we are born then we wouldnt be able to survive. we need development because if we grew we would also need to develop because we wouldn be able to survive with say the size heart and lungs we had when we were first born. lastly, we need the ability to adapt because if we lived in he artic where temperatures were below zero and our bodies didnt keep us warm with homeostasis we would, again not live.
- Donna W. period 4
Characteristics that are important for living things are: Reproduction,Energy,and cells. Living things need reproduction because we need to reproduce so we don't go extinct. If us living things reprooduce we won't really hsve to worry about extinction of our species. We need energy to keep us moving! To big things like running from predators to little things like picking food to eat. We need cells because we are made out of cells. To our hair to our skin. Those are pure cells. Or as Ms Mitsiadis calls them:The buliding blocks of our bodies.
Zoe.E period 4
The 3 characteristics of life that are necessary for survival are the cells and how they are organized, being able to adapt to any environment, and reproduction.
The cells are important for survival because cells are the building blocks of life. Everyone's body is made up of cells and without it, we wouldn't be able to function our bodies.
Adaptation is living organisms responds to their external environment, and is also important because if you want to survive, you have to be capable of adapting to any environment. For example, when it is raining outside, we adapt to the environment by bringing and umbrella or wearing a raincoat. Also when it's winter time, people must learn how to adapt then by staying warm and returning to their normal body temperature to survive.
Reproduction is the process of producing offspring which is an essential part of life. It's necessary because with reproduction, all living things, like humans and animals, would be extinct. Then there would be nothing and no one in this world and we wouldn't be here today.

three things that are needed for life is water, nurishment, and an enviorment. water is important because most of everything is made up of mostly water. nurishment in needed too because it gives the body its nutrision and energy. inviorments you have got to have since there is no way you can live floating in the middle of no where. you need a place to be.
period 2
Some characteristics of life that is absolutely necessary is reproduction, responds to stim uli, and cells. Reproduction means that the living organism makes its own kind from one generation to the next. The reason why its so important is because reproduction is necessary. Without it, the living organisms would die off, and become extinct. An example of reproduction is when humans, or animals have babies. Then, when the babies get older, they have babies and keeps the generations going. Stim uli is also important. It means responsivness. Living environments respond to their external environment. An example of this is that plants bend toward the sunlight. And the last thing is cells. Without cells we would be nothing. Every living organism has cells. Cells are the building blocks of life. Everthing needs cells to be alive.

one characteristic of life is a must have is food. If we didn't have food then our sugar levels will go down and you will faint and your electro lights would be out of wack. Another thing we need is sleep if we dont sleep for 10 or 11 days we can die, because your body never can rest. Another thing we need is oxgen no human can live without oxygen every living thing needs to breath.
joseph E. period 3
One process of life that we absolutely need is food. We need fluid in our bodies so water will help us to do that. We also need food. Food will keep us full. We also need oxygen. Without oxygen we wouldn't be able to breathe.
-Stephanie lizzul 903
Period #3
Three characteristics of life that are necessary are, water & food, reproduction and air.
Water is necessary because without it, all living creatures would die from dehydration. Without food, living organisms would die of starvation.
The ability to reproduce is necessary for survival because, without it no new generations would be born. This would make extinction a certain demise for all living organisms.
Lastly, Air is needed for survival because without it no organism would be able to breathe, causing them to die.
Daniel P. period 4
3 charactoristics we need to survive is food, water, and heat. We need food because we can starve to death and without food we will go hungry and that is not a good way to live. We need water so that way we cannot get dehidrated, many people can dye from dehidration so i think that to live we need to be hydrated. Also we need heat becuase if we are not nicely dress for cold weather than we can freeze to death, so with heat we could keep ourselves warm.
-isabela janashvili
The three characteristics of life that are absolutly necessary are cells, reproduction, and the ability to adapt.
We need the ability to adapt for one main reason. The reason being that we need to be eligible to adapt to our environment. We need to adapt to this place, or area so we can benefit from it. And get all the necessary resources we need in order to live our life.
Cells are a necessary item in our life because a cell is the basic need of anything that is living. In our bodies and other organisms bodies, everything is made up of a cell. In order to move or do anything, our body needs cells.
Lastly, we need to reproduce so our environment does not die out and become extinct. If it was not for reproduction then nothing would exsist on this planet, or anywhere.

One characteristic of life that is nessacary is cells,reproduction,and lastly growth and deveolpment. Cells are needed in the baby because they afre the building blocks of life. With the there would be no us. THe repreodction of ceells is also important because without reproduction we wouldnt have organs and all the necsscary things in our body to make it work properly. The last chararcteristic is the growth and develpoment of calls. This is important because cells are needed to grow and deveolp over time in order to make sure the organs and other necessary things in any organisim work properly.
One thing human life must need for survival is oxygen,without oxygen we wouldn't be able to breath and we need to breath to keep our organs working. You need organs, without organs your not really a living organism. You also need to learn how to adapt to certain obstacles that may come in your way.
Fredrick Ll. period#4
Three characteristics of life that I feel are absolutely necessary for survival are oxygen, water, food. You need water or you would dehidrate and die, tou need oxygen so you can breath, and you need food so that your body can conserve energy.
Alyssa L. Period 4
Three processes that are completely necessary for survival are growth and development, reproduction, and cells.
Without growth and development we would not know how to take care of ourselves, and you can't rely on people to live your own life for you forever. Growth and development also teaches you the responsibilities you have throughout life.
Reproduction is a necessity for survival because people don't live forever. Hence, we need more human lives to keep ourselves from becoming extinct. If people die, and no more babies are being born, then extinction is a major possibility.
Cells are a major part of survival because they help us live. They keep us going throughout the day.

Period 3.
One thing every living organism needs to survive is cells because without cells your body doesnt function.
Another is oxygen because without oxygen you will suffocate almost like in space without the right equipment.
And last is H2O because you need water so your body can stay hydrated.
Phillip Lluberes Period 3
The most important charactersitics of life are being made up of 1 or more cells, adaptations over times, and reproducing. It is important to have cells because they make up our skin, which protects our organs. It is also important to have cells because it is what we are made up of. Adapting to changes is important because it allows us to change, or evolve, and survive in our environments when they go through change. Finally, reproducing is important because we don't live forever and want to continue our species/kind.
-Danielle C.
Period 4
I think three characteristics of life that are absolutely necessary for survival is cells, reproduction, and growth and development. All living things are made up of cells. Cells are the building blocks of life and without them you wouldn't have the correct organs, bones, or body systems that the human body consists of. If a living thing does not have their body or structure it would be hard to go through everyday life without the tools that the body provides. A second important characteristic is reproduction. Reproduction is the process of producing one or more offspring of that type. Reproduction is necessary because you need different generations to live in the world that changes everyday. The third characteristic is growth and development. Growth and development is very important for survival because living things need the ability to change and adapt to its enviornment, especially when it changes. If you can't develop according to your surrondings you won't be able to survive.

Cells is needed to be catagorized as a living things. Every cell in a living thing as a job that let us live. A lot of cells together create tissues. A lot of tissues create organs such as the heart, brain, stomach etc [for humans] and when all these important items work together is an organ system. Those items was all created by a cell.
A living thing needs to reproduce there for their kind well be carried down for the years to come. Everyone knows that all living things will eventually die when their organs can't run our body anymore. If, all your species become extinct then, who would be there for the generations to come. If living things can't reproduce, there may not be me or you.
Also, one characteristic of lifr thatv is important is stimuli. Stimuli is the reaction you have to things. If you don't have stimuli, you would have no reaction to sounds, actions caused by another, etc and that may affect your body. Stimuli is a good thing to have. :]

Keep up the good work! It's great to see all your posts.
3 characteristics of life that are absolutelynecessary are cells, growth & development, and reproduction. I chose cells because they are the "building blocks of life", and they create everything. Because of them, they created cell tissues, organs, and many more. Another thing I picked was growing/ developing. I chose this because everyone needs to grow up, and unfortunately, eventually die. New babies will take our places in this process. If we didn't grow, everyone would be infants, and no one else would exist. Finally, the last thing that I chose was reproduction. Without reproduction, we would just grow to get old, die out, and there wouldn't be a next generation. Without reproduction, the entire human race would be extinct.
Three life processes that are absolutely necessary for survival are cells, reproduction, and growth and development. Cells are needed because they are the "building blocks of life", and without them, none of the things that are supposed to happen with our bodies would be completed. Reproduction is important because if there was no more reproducing, the human species would die off. And growth and development is also important because if you didn't grow, the necessary life cycles wouldn't happen and many processes would be stopped.

Their are many different types of characteristics of life that is necessary.
First, charateristic is Cells because we cant live if we dont have them since they do make our tissues which forms our organs. Cells are basicly the builing blocks of life and with out them we dont exist. All living things are made up of cells.
Secondly, I think reproduction. Reproduction is important because with out reproduction our species will be extinct, and if we reproduce then we will have more generations.
Third, I think food&water becuase with out food you most likely starve to death, and you need protein to grow healthy as possible, and with out water u will get over dehidrated which will also cause death their for its needed.
I picked these two becuase its the most thing i see threw out the day is food water and people which was obviously reproduction. Their are also thingys that are really important that aren't always seen. As for cells thats one that i wrote about thats not seen. Or thats wats people think. When people look at a living thingy sometimes it doesnt come to mind that they are looking at a cell.

Things we absolutly need as humans are:
-Water
-Energy
-Oxegen
-Food
We also need to adapt to stimulis and be able to compete with other species for survival.
I think that the main three things that we need is,
-oxygen
-water
-food
I believe that we need these things b.c they all connect to one or anotherm w|O water we would dehydratee.
We need oxygenn, b.c w|O oxygen we can't breathe.
The nutriants that are in food help you live and be healthy so im sure you need that
