Final answer:
Organisms need food for growth, energy, and essential nutrients.
Step-by-step explanation:
Organisms need food for several reasons. First, food is the source of energy required for growth and development. The body breaks down the molecules in food to release energy that is used for various bodily functions. Second, food provides the raw materials needed for producers (such as plants) to produce glucose through photosynthesis, which is then used by other organisms as a source of energy. Lastly, food also provides essential nutrients, such as vitamins and minerals, that are necessary for the proper functioning of the body.
