Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host ) and parasitoidism (which always does, eventually).
Predation is a short-term interaction, in which the predator, here an osprey, kills and eats its prey. Short-term interactions, including predation and pollination, are extremely important in ecology and evolution. These are short-lived in terms of the duration of a single interaction: a predator kills and eats a prey; a pollinator transfers ...
Hyperpredation, also known as hypopredation, is when a generalist predator increases its predation pressure as a result of the introduction of a substitute prey. [1] Hyperpredation has been proven, for instance, in lab settings using two hosts and a parasitoid wasp. [2] Prey that require more handling time than they are worth in terms of ...
Ecology; Ecology addresses the full scale of life, from tiny bacteria to processes that span the entire planet. Ecologists study many diverse and complex relations among species, such as predation and pollination. The diversity of life is organized into different habitats, from terrestrial to aquatic ecosystems.
Optimal foraging theory (OFT) is a behavioral ecology model that helps predict how an animal behaves when searching for food. Although obtaining food provides the animal with energy, searching for and capturing the food require both energy and time.
Intraguild predation is common in nature and widespread across communities and ecosystems. [2] Intraguild predators must share at least one prey species and usually occupy the same trophic guild, and the degree of IGP depends on factors such as the size, growth, and population density of the predators, as well as the population density and behavior of their shared prey.

Prey switching is frequency-dependent predation, where the predator preferentially consumes the most common type of prey. The phenomenon has also been described as apostatic selection, however the two terms are generally used to describe different parts of the same phenomenon.
The numerical response in ecology is the change in predator density as a function of change in prey density. The term numerical response was coined by M. E. Solomon in 1949. [ 1 ] It is associated with the functional response , which is the change in predator's rate of prey consumption with change in prey density.
