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.

Answer:
Mass extinction is when biodiversity or species in a living habitat decreases to about three-fourths of its original number or to none. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the rate of speciation. Mass extinctions are usually associated with organisms that are macroscopic rather than microscopic. Examples of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.
