The principal chemical compound that living things use to store energy is
A
DNA
B
ATP
C
H2O
D
CO2
Explanation: 

Detailed explanation-1: -Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

Detailed explanation-2: -Potential energy is stored in an ATP molecule. It is like a battery that is ready to be used. When the cell needs energy it will break a phosphate bond within the ATP molecule and release energy for the cell to use.

Detailed explanation-3: -The flow of energy through living organisms begins with photosynthesis. This process stores energy from sunlight in the chemical bonds of glucose. By breaking the chemical bonds in glucose, cells release the stored energy and make the ATP they need.
