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]
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.
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.
The iGEM (International Genetically Engineered Machine) competition is a worldwide synthetic biology competition that was initially aimed at undergraduate and 'overgraduate' university students, but has since expanded to include divisions for high school students, entrepreneurs, and community laboratories. iGEM is presented as "the heart of synthetic biology" - educating the next generation of ...

The crab-coral interaction described above is also an example of refuge from competition, since the herbivory of crabs on seaweed reduces competition between coral and seaweed. [12] Similarly, herbivory by sea urchins ( Strongylocentrotus droebachiensis ) on kelps ( Laminaria spp.) can protect mussels ( Modiolus modiolus ) from overgrowth by ...
The term "Allee principle" was introduced in the 1950s, a time when the field of ecology was heavily focused on the role of competition among and within species. [ 1 ] [ 3 ] The classical view of population dynamics stated that due to competition for resources, a population will experience a reduced overall growth rate at higher density and ...
