The Principle Of Competitive Exclusion Indicates That?
Posted on March 18, 2012.
Seems like C is the right answer
In ecology, the competitive exclusion principle,[1] sometimes referred to as Gause’s law of competitive exclusion or just Gause’s law,[2] is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are constant. When one species has even the slightest advantage or edge over another, then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other, leading to either the extinction of this competitor or an evolutionary or behavioral shift towards a different ecological niche. The principle has been paraphrased into the maxim “complete competitors cannot coexist”.[1]
