homeostasis

Explanation:

Homeostasis is the biological process by which living organisms maintain a stable internal environmetal condition despite changes in their external environment. Homeostasis is an important phenomenon for the optimal functioning of any living organism.

A vivid example of homeostatic process is the regulation of temperature in humans or some animals. Self-r regulating mechanisms help keep their temperature at a stable state irrespective of temperature changes in the external environment i.e. hot or cold external conditions. The steady state of internal temperature is very important for some physiological processes in living systems.
