Chapter 54, Problem 2TYU
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.

Students have asked these similar questions
BLANK between species with BLANK ecological niches means they are les likely to occur sympatrically
A) Competition; similar
B) Predation; similar
C) Competition; dissimilar
D) Predation; dissimilar
E) None of the above
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.
Which of the following can explain why species are able to coexist, even if the competitive exclusion principle is generally true?
a) Species may be competitively equivalent, with the outcome of each competitive encounter being essentially random.
b) Competitive exclusion may take many generations; prior to that point, there will be coexistence.
c) Spatial heterogeneity in the distribution and concentrations of limiting resources can result in variation in the strength of competition across the landscape.
