An apex predator, also known as a top predator or superpredator, is a predator [a] at the top of a food chain, without natural predators of its own. [ 6 ] [ 7 ] Apex predators are usually defined in terms of trophic dynamics , meaning that they occupy the highest trophic levels .
At the top of this food chain are apex predators such as lions. [130] Many predators however eat from multiple levels of the food chain; a carnivore may eat both secondary and tertiary consumers. [131] This means that many predators must contend with intraguild predation, where other predators kill and eat them.
Tertiary consumers, which are sometimes also known as apex predators, are hypercarnivorous or omnivorous animals usually at the top of food chains, capable of feeding on both secondary consumers and primary consumers. Tertiary consumers are usually the largest, strongest and most aggressive animal in the local environment.
Food chain length is another way of describing food webs as a measure of the number of species encountered as energy or nutrients move from the plants to top predators. [ 41 ] : 269 There are different ways of calculating food chain length depending on what parameters of the food web dynamic are being considered: connectance, energy, or ...
A carnivore at the top of the food chain (adults not preyed upon by other animals) is termed an apex predator, regardless of whether it is an obligate or facultative carnivore. In captivity or domestic settings, obligate carnivores like cats and crocodiles can, in principle, get all their required nutrients from processed food made from plant ...
A mesopredator is a predator that occupies a mid-ranking trophic level in a food web. [1] There is no standard definition of a mesopredator, but mesopredators are usually medium-sized carnivorous or omnivorous animals, such as raccoons, foxes, or coyotes. [2] [3] They are often defined by contrast from apex predators or prey in a particular ...
The team investigated the system designed to keep predatory doctors at bay, as well as past cases of sexual misconduct. Even the most high-profile doctors are among the initiators of unwanted ...
Raccoons (Procyon lotor) and skunks (Mephitis mephitis) are mesopredators.Here they share cat food in a suburban backyard.. The mesopredator release hypothesis is an ecological theory used to describe the interrelated population dynamics between apex predators and mesopredators within an ecosystem, such that a collapsing population of the former results in dramatically increased populations of ...
