How does the biologist determine whether a thing is living or nonliving?


A biologist will characterize a living organism (as opposed to nonliving) using these seven signs:

1 living things have highly organized, complex structures

2 living things maintain a chemical composition that is quite different from their surroundings

3 living things have the capacity to take in, transform, and use energy from the environment

4 living things can respond to stimuli

5 living things have the capacity to reproduce themselves

6 living things grow and develop

7 living things are well-suited to their environment
