Detailed explanation-1: -All big cats are examples of tertiary consumers. For example, lions, tigers, pumas, jaguars, etc. Furthermore, they are also apex predators, which imply that in their natural environment there are no other organisms that prey on them.

Detailed explanation-2: -Lions can eat fox and thus it will be on the next trophic level which is a tertiary consumer. A lion is a tertiary consumer in both grassland and forest ecosystems.

Detailed explanation-3: -Lions are consumers because they eat other things to obtain their energy. Primary consumers are animals that eat plants. Lions are classified as secondary consumers because they eat primary consumers.

Detailed explanation-4: -Ecosystems can also have tertiary consumers, carnivores that eat other carnivores. A bald eagle is an example of a tertiary consumer you might see near the coastal mangrove islands of the Everglades. Its diet includes predatory fish that eat algae-eating fish, as well as snakes that feed on grass-eating marsh rabbits.

Detailed explanation-5: -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.
