Everything that is alive needs energy. All animals, including people, get the energy they need from food. If you think about the human body as an amazing machine that
can do all kinds of wonderful things for us, think of food as the fuel that helps keep it running.
Plants use sunlight to make their own food.
Animals are not able to do that. Some animals eat plants. Some animals eat other animals. Some animals, like people, eat both plants and animals.
Since plants make their own food using sunlight, the sun’s energy is found in plants. When we eat plants, like fruits and vegetables, we get more of the sun’s energy that when we eat animals. Energy is very strong in the sun. It loses a lot of its strength by the time it goes into a plant. By the time an animal eats a plant, the energy is even less strong. The animal has also used ienergy to find the plant to eat. When a second animal eats the first animal, it gets even less energy than the first animal got. The second animal has had to find and chase down the first animal, and so it has also used up a lot of energy to get more.
