Final answer:
Organisms eat food to provide energy, obtain essential nutrients, and acquire molecules that cannot be produced internally.
Step-by-step explanation:
Why do organisms eat food?
Organisms eat food for several reasons. First, food provides the necessary energy for organisms to carry out their daily functions. The process of breaking down food releases energy in the form of molecules called ATP, which is used to power cells. Second, food contains essential nutrients such as proteins, carbohydrates, fats, vitamins, and minerals that are necessary for growth, repair, and maintenance of the body. Lastly, organisms eat food to obtain molecules that cannot be produced by their own bodies, such as certain amino acids and fatty acids.
