Summary Introduction
To review:
The reason for the fact that hawks and owls both feed on small mammals to sustain their respective populations without causing competitive exclusion.
Introduction:
The competitive exclusion is also referred to as Gause's law of competitive exclusion. This states that two existing species competing for the same resource cannot coexist at same ecological niche if other ecological factors remain constant.
