Competition is an interaction between organisms or species in which both require one or more resources that are in limited supply (such as food, water, or territory). [1] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other. [2]
Competition within, between, and among species is one of the most important forces in biology, especially in the field of ecology. [5]Competition between members of a species ("intraspecific") for resources such as food, water, territory, and sunlight may result in an increase in the frequency of a variant of the species best suited for survival and reproduction until its fixation within a ...
Contest competition is the opposite of scramble competition, a situation in which available resources are shared equally among individuals. As contest competition allows the monopolization of resources, offspring will typically always be produced and survive until adulthood independent of the population size, resulting in stable population ...
Competition is often for a resource such as food, water, or territory in limited supply, or for access to females for reproduction. [18] Competition among members of the same species is known as intraspecific competition , while competition between individuals of different species is known as interspecific competition .
Interference competition is the process by which individuals directly compete with one another in pursuit of a resource. It can involve fighting, stealing or ritualised combat. Direct intraspecific competition also includes animals claiming a territory which then excludes other animals from
Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. food or living space). This can be contrasted with mutualism, a type of symbiosis. Competition between members of the same species is called intraspecific competition.
Yellow adapts to a new niche restricted to the top and bottom and avoiding competition. In ecology , the competitive exclusion principle , [ 1 ] sometimes referred to as Gause's law , [ 2 ] is a proposition that two species which compete for the same limited resource cannot coexist at constant population values.
Coexistence theory attempts to explain the paradox of the plankton-- how can ecologically similar species coexist without competitively excluding each other?. Coexistence theory is a framework to understand how competitor traits can maintain species diversity and stave-off competitive exclusion even among similar species living in ecologically similar environments.
