Context: Food supplies an organism with many small, energy-rich molecules. These molecules are taken in by the organism's cells. Inside cells, the molecules from food are broken down to release energy that cells can use. This energy powers cell processes that allow the entire organism to grow and live.
All organisms need food for energy. But how does an organism's body actually get energy out of food?
Select the true statement.
A. Cells usually take in large food molecules.
B. Cells use energy to promote the organism's growth.
