Sometimes. The animal eating plants is the primary consumer, the animal eating that animal the secondary, and finally the animal eating that one is the tertiary... so if a fis â¦ h eats algae, is then eaten by another fish, and that fish is eaten by a dolphin, then the dolphin is the tertiary consumer.
Third-level consumers are any organisms big enough to obtain energy by feeding off lower-level consumers. These are also called tertiary consumers. For example, in a forest ecosystem, snakes eat toads. Heron and large fish, such as bass and walleye, consume smaller fish, frogs and crayfish. Some ecosystems have four or more levels of consumers. Owls, high-level forest predators, go after third level consumers such as snakes and other smaller animals.
