Definitions for apex predator
This page provides all possible meanings and translations of the word apex predator
An animal atop the food chain, preying but not prey.
Apex predators are predators with few to no predators of their own, residing at the top of their food chain. Zoologists define predation as the killing and consumption of another organism. In this context, "apex predator" is usually defined in terms of trophic dynamics. Apex predator species occupy the highest trophic level and have a crucial role in maintaining the health of their ecosystems. One study of marine food webs defined apex predators as greater than trophic level four. The apex predator concept is commonly applied in wildlife management, conservation, and ecotourism. Food chains are often far shorter on land, with the top of the food chain limited to the third trophic level, as where such predators as the big cats, crocodilians, hyenas, wolves, or giant constrictor snakes prey upon large herbivores. Apex predators do not need to be hypercarnivores. For example, grizzly bears and humans are each apex predators and are omnivores.
