The Form of Energy Primarily Used by Living Organisms to Do

Question

The form of energy primarily used by living organisms to do work is
A) heat.
B) chemical.
C) sound.
D) light.
E) gravity.

Accepted Answer

Living organisms primarily use chemical energy in the form of ATP (adenosine triphosphate) to do work. This energy is obtained through the breakdown of food molecules and is used for processes such as movement, growth, and reproduction. Heat, sound, light, and gravity can all have physiological effects on organisms, but they are not typically used as a form of energy to do work.
