An example of direct competition. Intraspecific competition is an interaction in population ecology , whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce. [ 1 ]
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 among members of the same species is known as intraspecific competition, while competition between individuals of different species is known as interspecific competition. According to the competitive exclusion principle , species less suited to compete for resources must either adapt or die out , although competitive exclusion is ...
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 .
This model conditions for coexistence can be directly related to the general coexistence criterion: intraspecific competition, α jj, must be greater than interspecific competition, α ij. The direct expressions for intraspecific and interspecific competition coefficients from the interaction between shared predators and resources are
The best-known example is the so-called "paradox of the plankton". [6] All plankton species live on a very limited number of resources, primarily solar energy and minerals dissolved in the water. According to the competitive exclusion principle, only a small number of plankton species should be able to coexist on these resources.
Interspecific competition, when individuals of different species compete for the same resource in an ecosystem; Interspecific feeding, when adults of one species feed the young of another species; Interspecific hybridization, when two species within the same genus generate offspring. Offspring may develop into adults but may be sterile.
In other words, intraspecific competition must exceed interspecific competition. [7] For example, jackrabbits living in the same area compete for food and nesting grounds. Such competition within the same species is called intraspecific competition, which limits the growth of the species itself. Members from different species can also compete.
