A food chain contains several trophic levels. These trophic levels separate various types of organisms. A tertiary consumer is a fourth trophic level after producers, primary consumers, and secondary consumers.
Tertiary consumers eat primary and secondary consumers as their main source of food. These organisms are sometimes referred to as apex predators as they are normally at the top of food chains, feeding on both primary and secondary consumers.
Tertiary consumers can be carnivores or omnivores. Their diet can comprise only meat or include plants as well. A hawk, for example, can feed on primary consumers such as birds, as well as secondary consumers such as snakes.
Let’s look at some other examples before we explore the functions of tertiary consumers. Many organisms, both in terrestrial and aquatic ecosystems, are considered to be tertiary consumers. Here are some of them:
1. Humans
Humans are largely omnivorous. They eat both plants and animals. Moreover, they have a wide-ranging diet and hence consume foods from virtually all trophic levels. We even consume decomposers such as mushrooms.
If you choose to be a vegetarian, you would be considered to be a primary consumer, thanks to the fact that you only consume plant materials. But if you also choose to eat chicken that only feeds on grain, you would fit in the secondary consumer category.
However, if the chicken also feeds on insects, then you would be a tertiary consumer. In light of the fact that humans can kill any animal using weapons, they are of considered as apex predators.
2. Big Cats like Lions and Tigers
Lions, tigers, leopards and other big cats are classed as tertiary consumers. Except for the leopard, the big cats are also apex predators. While the cats have no predators in their natural habitat, leopard is sometimes predated by lions and tigers.
