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]
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.
Competition can be defined as an interaction between organisms or species, in which the fitness of one is lowered by the presence of another. Competition is often for a resource such as food , water , or territory in limited supply, or for access to females for reproduction. [ 18 ]
Exploitative competition involves individuals depleting a shared resource and both suffering a loss in fitness as a result. The organisms may not actually come into contact and only interact via the shared resource indirectly. For instance, exploitative competition has been shown experimentally between juvenile wolf spiders (Schizocosa ocreata ...
Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). [1] Competition can arise between entities such as organisms, individuals, economic and social groups, etc.
Paramecium aurelia and Paramecium caudatum grow well individually, but when they compete for the same resources, P. aurelia outcompetes P. caudatum.. Based on field observations, Joseph Grinnell formulated the principle of competitive exclusion in 1904: "Two species of approximately the same food habits are not likely to remain long evenly balanced in numbers in the same region.
The populations of all species will be bounded between 0 and 1 at all times (0 ≤ x i ≤ 1, for all i) as long as the populations started out positive. Smale [ 3 ] showed that Lotka–Volterra systems that meet the above conditions and have five or more species ( N ≥ 5) can exhibit any asymptotic behavior, including a fixed point , a limit ...
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.
