Detailed explanation-1: -Tertiary consumers eat the secondary consumers. They are at the fourth trophic level. In the desert ecosystem, an owl or eagle may prey on a snake. There may be more levels of consumers before a chain finally reaches its top predator. Top predators, also called apex predators, eat other consumers.

Detailed explanation-2: -Fourth Trophic Level: Tertiary Consumers Tertiary consumers eat primary and secondary consumers to fulfill their nutrient needs. They obtain their energies from meat, and include animals like hyenas, dolphins, and sharks.

Detailed explanation-3: -Tertiary consumers receive 10% of the energy available at the secondary level (0.1% of the original energy). As a result, tertiary consumers have the least amount of energy and are therefore at the top of the pyramid (the smallest part).

Detailed explanation-4: -The base trophic level is the producers, which make their own food. These are fed on by primary consumers, which are then eaten by secondary consumers. The organisms that prey on the secondary consumers are called the tertiary consumers. Some examples of tertiary consumers are sea turtles, sea lions, hawks, and foxes.
