Do you like playing soccer or watching TV? Whatever you’re doing, you need energy to do it.
All living things derive energy from the food they consume. As food passes through the system, some of it is digested, in a physical process that releases energy. That energy is passed along in a community via food chains and food webs. Here’s how those function:
1. Plants convert the Sun’s energy into food—starch—which they store in their leaves.
2. Some of this energy is passed along as food for animals. For example, many plants are eaten by herbivorous (plant-eating) animals such as rabbits.
3. Herbivores, in turn, are eaten by carnivores (meat-eaters), like snakes, or omnivores (plant- and animal-eaters), like bears.
4. These animals are, in turn, eaten by other animals.
