Question

which characteristic of life best describes the process of homeostasis?

Explanation:

Reproducing is about creating offspring, growing and developing is about an organism's physical change over time, and using energy is related to metabolic processes. But only responding to the environment directly relates to maintaining internal stability which is homeostasis.
