Most food chains have more than one consumer. The consumers are described by how high up the food chain they are. This is shown in the diagram below.

• The consumer that eats the producer is called the primary consumer. All herbivores are primary consumers.

• Whatever eats the primary consumer is called the secondary consumer.

• Whatever eats the secondary consumer is called the tertiary consumer.

• If there is any animal that is large and dangerous enough to eat the tertiary consumer, it is called a quaternary consumer.

If an animal is at the top of a food chain and has no natural predators, it can also be called an apex predator.
