What are the 4 characteristics of a living organism?

Answer 1

They Move They Reproduce They are Sensitive They take in Nutrients They Excrete They Respire (breathe) They Grow

You can remember it by using the first letters of each word, like this:

"Mrs Nerg" - Move, Reproduce, Sensitive; Nutrients, Excrete, Respire, Grow

or you can use "Mrs Gren" and remember Move, Reproduce, Sensitive, Grow, Respire, Excrete, Nutrients

Living organisms have characteristics of life that non-living organisms do not have. These characteristics are:

1) Responds to Stimuli- If there is danger, a living organism will run away. If it is hungry, the organism will move to a spot where there's food. Stimuli is what makes the organism respond.

2) Uses Energy- All living things use energy. A human uses energy most often by walking. A horse uses energy to run about a corral.

3) Has Cells- Cells are the basic building blocks of life. All living organisms must have at least one cell to be alive.

4) Reproduces- In order for a species to survive, they must reproduce. All living organisms reproduce, or have offspring.

5) Growth and Development- All living organisms grow and develop to their surroundings. Non-living organisms cannot grow or develop. All living organisms eventually die, while non-living organisms do not. They remain for as long as they are not rusted or rotting.

Well first off, if something is nonliving, it us not an organism. There is no such thing as a nonliving organism, but the difference between living and nonliving things is pretty clear and easy to understand.

There are six rules to use (and all must be met) to determine if something is living or not:

1) can it move on its own?

2) does it consume some form of energy?

3) does it use some form if excretion?

4) can it reproduce?

5) does it exchange gases with the atmosphere?

6) is it made of organic cells?

If all of these requirements are met, then most likely the thing is alive.
