Define homeostasis. Why most organisms continuously acquire energy and materials from the external environment to maintain homeostasis?
homeostasis definition: It is the ability of a living organism, cell, or group of cells to keep the conditions inside it the same irrespective of any changes in the conditions
It is necessary to constantly acquire energy from the external
environment because most organisms are constantly using energy. If
energy is not taken taken in from outside your body, eventually the
organism will not have any energy to do normal reactions in the
body and to function. Our bodies thrive off energy. If energy is
lost, we need to gain more to make up for the loss so that we can
keep functioning. The state in which everything is functioning
properly is called homeostasis.
