Competition

Competition

Intraspecific: Individuals compete for resources, who are the same species. Availability of the resources will determine the size of that population. The larger the availability of resources, the larger the population. Interspecific: Individuals compete for resources who are different species. Individuals of different species occupy the same niche will have a competitive advantage over another. One population grows, one shrinks. Competitive exclusion principle: Where populations of two species initially occupy the same niche, one normally has a competitive advantage. The population of this species gradually increases size while the other population will diminish. Conditions remain the same, this leads to the removal of one species. Known as competitive exclusion principle – where two species compete for limited resources, one uses resources most effectively ultimately eliminate the other.
