What term describes the carnivores that consume other carnivores?

The term that describes carnivores that consume other carnivores is "tertiary consumers." In ecological terms, these organisms occupy a third trophic level above primary consumers (herbivores) and secondary consumers (which are typically carnivores that feed on herbivores). Tertiary consumers often play a crucial role in the food web as they help regulate populations of secondary consumers, which in turn affects the entire ecosystem.

Tertiary consumers are usually larger and more specialized predators that can hunt and eat other carnivores, thus they are positioned higher in the food chain. This concept emphasizes the flow of energy and nutrients through different levels in an ecosystem.

The other choices refer to different levels in the food chain: primary consumers are herbivores that eat plants; secondary consumers primarily eat primary consumers; while quaternary consumers, which are not typically mentioned for simpler food chains, would represent another trophic level above tertiary consumers, often referring to apex predators that have few or no natural enemies.
