The sources of food of an organism contain carbohydrates, lipids, nitrogenous substances and other compounds. The metabolism of these, in the digestive tract yields substances required by the body such as ATP, water, nitrogen and more. After metabolism, the excess and toxic substances are excreted from the body in the form of wastes.
