  2. Competition (biology) - Wikipedia

    en.wikipedia.org/wiki/Competition_(biology)

    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]

  3. Contest competition - Wikipedia

    en.wikipedia.org/wiki/Contest_competition

    Contest competition is the opposite of scramble competition, a situation in which available resources are shared equally among individuals. As contest competition allows the monopolization of resources, offspring will typically always be produced and survive until adulthood independent of the population size, resulting in stable population ...

  4. Intraspecific competition - Wikipedia

    en.wikipedia.org/wiki/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 ]

  5. Competition - Wikipedia

    en.wikipedia.org/wiki/Competition

    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 ...

  6. Biological interaction - Wikipedia

    en.wikipedia.org/wiki/Biological_interaction

    Predation is a short-term interaction, in which the predator, here an osprey, kills and eats its prey. Short-term interactions, including predation and pollination, are extremely important in ecology and evolution. These are short-lived in terms of the duration of a single interaction: a predator kills and eats a prey; a pollinator transfers ...

  7. Interspecific competition - Wikipedia

    en.wikipedia.org/wiki/Interspecific_competition

    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.

  8. Competitive exclusion principle - Wikipedia

    en.wikipedia.org/wiki/Competitive_exclusion...

    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.

  9. Coexistence theory - Wikipedia

    en.wikipedia.org/wiki/Coexistence_theory

    For example, if annual plants germinate in different years, then when it is a good year to germinate, species will be competing predominately with members of the same species. Thus, if a species becomes rare, individuals will experience little competition when they germinate whereas they would experience high competition if they were abundant.
