AP BIOLOGY

Detailed explanation-1: -Answer and Explanation: The trophic level that is most vulnerable to extinction is tertiary consumers. Tertiary consumers are top predators in the ecosystem and are the highest level of the food web.

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: -Eliminating the large predators at the top of the food chain, the “apex species, ” may be humans’ most serious impact on nature, according to one study. These large species are more vulnerable because they live longer, reproduce more slowly, have small populations, and need more food and a greater habitat area.

Detailed explanation-4: -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-5: -Tertiary consumers often occupy the top trophic level, and so are predated by no other animals; in this case they are called “apex predators”. However, when they die their bodies will be consumed by scavengers and decomposers.
