<P> An apex predator , also known as an alpha predator or top predator , is a predator at the top of a food chain , upon which no other animals prey . Apex predators are usually defined in terms of trophic dynamics , meaning that they occupy the highest trophic levels and serve as keystone species , vital to their ecosystems . One study of marine food webs defined apex predators as those feeding at trophic levels above four . Food chains are often far shorter on land , usually limited to the third trophic level -- for example , wolves prey mostly upon large herbivores . The apex predator concept is applied in wildlife management , conservation and ecotourism . </P>
