168 All green plants use energy from the sun to make food in their leaves. Plants are called producers because they can make food for themselves. Animals cannot make food for themselves: they have to eat plants or other animals to get the energy they need for life. Animals are called consumers. An animal that eats only plants is called a herbivore. An animal that eats only other animals is called a carnivore. An animal that will eat plants or animals is called an omnivore. In a food chain, arrows are used to show which way the energy is going. The first step in the food chain is the producer (plant). An animal which eats the plant is called the primary consumer. An animal which eats the primary consumer is called the secondary consumer. Animals which prey on other animals are known as predators, and the animals that they prey on are known as their prey. A predator that nothing else preys on is known as the top predator. Drag the Tiles into position to put the segments of text into the correct order.
