Apex predators occupy the highest trophic positions in food webs and serve profoundly important roles in ecological and evolutionary processes, shaping and re-shaping the traits of prey and how they interact with one another and the ecosystem. Predators have profound effects throughout their ecosystems. Dispersing rich nutrients and seeds from foraging, they influence the structure of ecosystems. And, by controlling the distribution, abundance, and diversity of their prey, they regulate lower species in the food chain, an effect known as trophic cascades. Many ecologists think that predators can boost biodiversity by hunting just enough of one prey species to make room in the ecosystem for another competing prey species to coexist. But predators can also harm biodiversity by hunting prey species to extinction. According to the keystone predator theory, top predators can prevent any one prey species from becoming too abundant and outcompeting all the other prey species, which should generally increase the diversity of the species at low levels of the food chain. Predators can increase diversity in communities by preying on competitive dominant species or by reducing consumer pressure on foundation species. Predators in marine, freshwater, and terrestrial environments may affect prey populations and communities by consuming lower trophic levels or by altering prey traits including behavior, morphology, or habitat use. Of course predators consume prey, but in doing so, they may have broader impacts on communities as a whole. That is to say, predators help to maintain a balance among organisms, both by consuming prey and by altering prey behavior and prey habitat selection. Predators are essential to ecosystems because they regulate prey populations. Without predators, prey can become over-abundant. This can result in damage to local plants, as well as disease outbreaks that can spread to domesticated animals. Many ecologists think that predators can boost biodiversity by hunting just enough of one prey species to make room in the ecosystem for another competing prey species to coexist. But predators can also harm biodiversity by hunting prey species to extinction. Predatory vertebrates and invertebrates provide important ecosystem services due to the consumption of pests. However, beneficial invertebrates and crop seeds were often consumed to a similar or even higher extent than harmful invertebrates or weed seeds. A predator is an organism that consumes all or part of the body of another living or recently killed organism, which is its prey. “Living or recently killed" distinguishes predators from decomposers, such as fungi and bacteria that break down the leftover remains of organisms that have died.
