Detailed explanation-3: -The tertiary consumer is also referred to as the apex predator. Such consumers typically exist at the very top of every ecological food chain. Moreover, a food chain usually consists of three types of consumers-primary, secondary, and tertiary consumers respectively.

Detailed explanation-4: -Tertiary consumers are preyed on by quaternary consumers. These quaternary consumers are often the apex predators, which means that they do not have any predators in the ecosystem. Some examples of quaternary consumers are lions, polar bears, sharks, and hawks.

Detailed explanation-5: -Rabbits, consuming grass are an example of primary consumers; snakes, consuming rabbits are an example of secondary consumers while owls, consuming snakes are an example of tertiary consumers.
