what possible outcome(s) can result from intense competition between two species
Competition (biology) According to the competitive exclusion principle, species less suited to compete for resources should either adapt or die out, although competitive exclusion is rarely found in natural ecosystems. According to evolutionary theory, this competition within and between species for resources is important in natural selection. However, competition may play less of a role than expansion among larger clades;[3] this is termed the 'Room to Roam' hypothesis.[2]
