Question

Quizplus · 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.
