Explanation:
The principle of competitive exclusion states that two species cannot occupy the same niche.
<h3>
What is competitive exclusion?</h3>
- Two species cannot coexist in the same ecological niche for very long without one becoming extinct or being driven out because of competition for limited resources.
- In Britain, the red squirrels have displaced the grey squirrels as an example of competitive exclusion.
- Due to diseases, competitive exclusion, and the elimination of hazelnuts, there were fewer red squirrels.
- Red squirrels were eventually displaced by gray squirrels, who quickly adjusted to their surroundings.
- Two species with identical niches cannot survive indefinitely, according to the "competitive exclusion principle" (CEP).
- According to the competitive exclusion principle, only one conclusion is feasible when two competing life forms try to inhabit the same niche: One of them will extirpate the other.
