5.      Why might the outcome of competition between two species be different under different conditions?

Apr 14th, 2015


 Competition;

Competition occurs indirectly when two or more organismic. units use the same resources and when those resources are in short supply. Such a process involving resource depression or depletion has been labeled consumptive or (exploitation competition). Competition may also occur through more direct interactions such as in interspecific territoriality or in the production of toxins, in which case it is termed interference competition. Competition for space, as in the rocky intertidal, often mediated by who gets there first, has been termed preemptive competition. Interaction between the two organismic units reduces the fitness or equilibrium population density. This can occur in several ways. By requiring that an organismic unit expend some of its time, matter, or energy on competition or the avoidance of competition. A competitor may reduce the amounts left for reproduction. By using up or occupying some of a scarce resource. competitors directly reduce the amount available. To other organismic units. Mechanisms of interference competition. such as interspecific territoriality. will be favored by natural selection only when there is a potential for overlap in the use of limited resources at the outset . (when exploitation competition is potentially possible)...........................
