Consumer–resource interactions are the core motif of ecological food chains or food webs, [1] and are an umbrella term for a variety of more specialized types of biological species interactions including prey-predator (see predation), host-parasite (see parasitism), plant-herbivore and victim-exploiter systems.
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 .
Solitary predator: a polar bear feeds on a bearded seal it has killed. Social predators: meat ants cooperate to feed on a cicada far larger than themselves. Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey.
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...

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 ...
Species are grouped trophically on the left, however distinctions such as herbivore and predator are merely the simplest definitions. Trophic species are a scientific grouping of organisms according to their shared trophic (feeding) positions in a food web or food chain. Trophic species have identical prey and a shared set of predators in the ...
