Transcription: Organisms need food for energy, growth, and repair of old and damaged tissues. Most animals eat plants or other animals, so their food is made up of large, complex molecules. These must be digested, broken down, to simpler, smaller molecules before they can be absorbed and carried to all parts of the body. Proteins are broken down into amino acids. Carbohydrates are broken down into simple sugars. Fats are broken down into fatty acids and glycerol.
