The process by which organisms keep everything inside their bodies within certain limits is called

a) homeostasis.

b) evolution.

c) metabolism.

d) photosynthesis.

The correct answer would be A) homeostasis.

Homeostasis can be defined as the state in which body or living being tends to maintain the internal environment at relatively stable equilibrium.

Blood sugar levels, body temperature, pH, fluid balance, et cetera are few variables which are required to maintain within the pre-set limits or homeostatic range in order to achieve optimum functioning of the organism.

For example, in human beings the body tries to maintain internal temperature at around 37°C.

Nervous system and endocrine system are the main regulators of the homeostasis in human beings.
