　　Warming up by learning about animals
　　Animals are living things. Plants can make their own food or
　　energy from the light of the sun, but animals can't do this.
　　Animals have to eat plants or other animals to get energy to live.
　　Some animals eat only plants. We say that these animals are herbivores. Some animals eat onlymeat. We say that these animals are carnivores. Some animals eat both plants and meat. We say that these animals are omnivores. Plants can't move around, but most animals can move around. Animals are divided into groups.
