Which of the following statements is consistent with the principle of competitive exclusion? the random distribution of one competing species will have a positive impact on the population growth of the other competing species. bird species generally do not compete for nesting sites. even a slight reproductive advantage will eventually lead to the elimination of the less well adapted of two competing species. two species with the same fundamental niche will exclude other competing species. natural selection tends to increase competition between related species.

Even a slight reproductive advantage will eventually lead to the elimination of the less well adapted of two competing species

Explanation:

The competitive exclusion describes relationship between two species that compete for the limiting sources, and cannot coexist. It is enough for one species to have slightly advantage to be dominant over the other. As a consequence, other species (the weaker one) will be extincted (shift to a different ecological niche).

answer: a. a gene that causes a specific trait.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
