Plants are special living things. They are special because they can make their own food using energy from the sun. Plants are primary producers that produce food from sunlight, carbon dioxide, and water.
Animals cannot make their own food. Animals are consumers because they must consume, or eat, to get energy to live. Some animals eat plants. Some animals eat other animals.
When an animal eats food, some of the food's energy is used to carry out the animal's life processes. Animals need energy to breathe, keep the heart beating, and excrete wastes, as well as to move around. Whatever food energy isn't used by the animal is stored in its tissues.
