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.
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 ]
For example, a slight modification of the assumption of how growth and body size are related leads to a different conclusion, namely that, for a given ecosystem, a certain range of species may coexist while others become outcompeted. [10] [11] One of the primary ways niche-sharing species can coexist is the competition-colonization trade-off ...
Some examples of non-trophic interactions are habitat modification, mutualism and competition for space. It has been suggested recently that non-trophic interactions can indirectly affect food web topology and trophic dynamics by affecting the species in the network and the strength of trophic links.
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 ...
Scientists have identified several new marine species in a pristine underwater ecosystem recently discovered in international waters -- and they expect to find more. Modern technology that allows ...
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.
