During recess, children are trying to balance a seesaw. if one side is too low, a heavier child will get off and be replaced by a lighter child; if one side is too high, a lighter child will be replaced by a heavier one. the children’s behavior is similar to our biological states as they try to create:

Equilibrium.

Explanation:

Our body seeks to keep its internal functions in balance, even with variations in the environment in which it finds itself. This balance is called homeostasis and can be observed when our body tries to adapt to cold, hot days, reduced food and water, physical effort, among others.

An example of this can be seen in the question above, where an individual seeks to keep the two sides of a seesaw in balance.
