Ecological interactions are some of the basic ecological processes that dictate ecosystems and, by default, lead to distribution and abundance among species. There include mutualism, commensalism, competition, predation, and parasitism. Mutualism is an interaction between two species in which both reap benefits, such as when bees pollinate flowers. In commensalism, one species benefits while it does not affect the other species, hence barnacles attach themselves to whales. Completion takes place where species are competing for the same resources, usually to the disadvantage of the poorer competitor. Predation is a form of feeding where one species feeds upon another, such as wolves feeding on deer to regulate the population of prey. In parasitism, one organism benefits by the cost of another, such as where ticks feed on mammals.

They form the basis of conservation practices as well as ecosystem management. They define community organization and energy as well as nutrient flow. For instance, loss of keystone species greatly changes the ecosystem since it guides it. Climate as well as human interference interferes with these interactions in order to result in biodiversity loss as well as changed functions of ecosystems. These interactions, therefore, must be considered by any conservation practice to ensure sustainability in an ecosystem.
