In a community with limited resources, the less vigorous species are eliminated due to
In a community with limited resources, organisms vie for essential resources like food, water, and space. The less vigorous, or competitively inferior, species are unable to acquire resources as efficiently as the superior competitors. This intense pressure leads to the decline and eventual local elimination of the less vigorous species, a concept known as competitive exclusion.
A. While disease can impact populations and even drive species to extinction, it is not the primary mechanism by which less vigorous species are consistently eliminated in the specific context of limited resources and a general community setting. Competition for limited resources is a more direct and universal ecological principle in this scenario.
B. Drought is an environmental stressor that makes resources (specifically water) more scarce, which in turn intensifies competition for those limited resources, but it is the resulting competition that directly leads to the elimination of the less vigorous species, not the drought itself as a direct cause in all scenarios.
D. Natality refers to the birth rate of a population. In a resource-limited environment, natality is likely to decrease due to competitive pressure, but it is a consequence of the limited resources and competition, not the cause of the less vigorous species' elimination.
