What is the term used to describe the balance that living things maintain with their environment?

The term that describes the balance that living things maintain with their environment is "homeostasis." This concept refers to the processes and mechanisms that organisms use to regulate their internal environment in order to maintain stable, constant conditions despite changes in the external environment. For example, humans maintain a stable body temperature, pH levels, and electrolyte balance, which are all critical for survival.

Homeostasis involves various physiological processes that adjust to internal and external stimuli, ensuring that the organism functions optimally. It is a foundational principle in biology that highlights the dynamic interactions between an organism and its surroundings, allowing it to adapt to various environmental challenges while sustaining life.
