Secondary consumers include reptiles, carnivores, small predators and insectivores. Animals at this level include different frog species, small snakes, large insects and birds of prey like eagles and vultures. Tertiary consumers include large snakes like the boa constrictor, and jaguar. Other large animals such as the Indian elephant or African forest elephant, gorillas or orangutans, and tapirs tend to feed on vines, fruits, or insects.
The next link in the chain is animals that eat herbivores. These are called secondary consumers. This is like a hawk that eats the hare. The Arctic wolf is a carnivore and is known as a tertiary consumer. This means that they exist in the top level in a food chain. An example of an animal that is beneath the Arctic wolf on the food chain would be the caribou, which is one of its most hunted food sources.
