The principle of competitive exclusion states that
- (A) two .species car. not coexist in the same habitat.
- (B) competition between two species always causes extinction or emigration of one species.
- (C) two species that have exactly the same niche cannot coexist in a community.
- (D) two species will stop reproducing until one species leaves the habitat.

According to the competitive exclusion principle, two species cannot exist together if they occupy the same niche. Either they diverge their niches so they can coexist or one species will die out.All of the following are consistent with the principle of competitive exclusion EXCEPT
Select one:
a. Birds and bats both consume flying insects, but birds are active in the day and bats are active at night.
b. Two species that share the same niche will exclude other competing species.
c. Different bird species forage for insects in different parts of the same tree.
d. When two species of Paramecium are grown in the same medium, one strain will eventually eliminate its competitor.
What is the principle that teaches us that two species cannot coexist in the exact same niche in the same habitat.This is because species with same niches have comparable requirements, which implies they would fight for the same resources.
If the human species were to suffer a population crash, what are three species that might move in to occupy part of our ecological niche?
