Eating is the ingestion of food to provide for all humans and animals nutritional needs, particularly for energy and growth. Animals and other heterotrophs must eat in order to survive: carnivores eat other animals, herbivores eat plants, and omnivores consume a mixture of both. Eating is an activity of daily living.
