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]
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 ]
In ecology, contest competition refers to a situation where available resources, such as food and mates, are utilized only by one or a few individuals, thus preventing development or reproduction of other individuals. It refers to a hypothetical situation in which several individuals stage a contest for which one eventually emerges victorious.
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.
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.
PINEHURST, N.C. — Kids don’t really write “What I did for my summer vacation” essays anymore. But even if they did, it’s a safe bet that no one at Cheyenne Mountain High School would ...
In today’s globalized economy, technological competition has become a high-stakes geopolitical battleground. We don’t have to guess what America’s adversaries desire or intend. They tell us.
Competition among plants for light is size-asymmetric because of the directionality of its supply. [2] Higher leaves shade lower leaves but not vice versa. Competition for nutrients appears to be relatively size-symmetric, [9] although it has been hypothesized that a patchy distribution of nutrients in the soil may lead to size asymmetry in competition among roots.
