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 statements is correct regarding the competitive exclusion concept? a. multiple species can’t share the exact same niche within a community b. the realized niche of a species is different from its fundamental niche. c. competition within a population results in the success of the best-adapted individuals. d. two species cannot coexist within the same habitat.
Competitive exclusion occurs under the following conditions: a. when fundamental niches overlap and competition is asymmetric b. when realized niches overlap and competition is asymmetric c. when fundamental niches overlap and competition is symmetric d. when realized niches overlap and competition is symmetric e. when competition is excluded because niches do not overlap
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. choose all the answers that apply.
A particular species of butterfly is capable of surviving and reproducing both in open grasslands and in forested habitats. However, in the forested habitats this butterfly is heavily predated (eaten) by a forest bird species, so the beetle species avoids these areas and is generally found only in grasslands. Which of the following statements are true? Answer choices: A. The butterfly's realized niche includes both grasslands and forested habitats. B. The butterfly's fundamental niche includes only grasslands. C. The butterfly's realized niche includes only grasslands. D. The butterfly's fundamental niche includes both grasslands and forested habitats E. The butterfly and the forest bird species are in competition.
A niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.
Which of the following statements is not true of an ecological niche?a. A niche includes the physical environment, such as climate and water availability.b. A niche includes predators and parasites.c. Niche overlap may help to drive evolution.d. Two species cannot have overlapping niches.
An ecologist visiting an island finds two species of birds, one of which has a slightly larger bill than the other. Interpret this finding with respect to the ecological niche and the competitive exclusion principle, and explain both concepts.
A niche is loosely defined as an organism's role in its environment, which can include factors like, feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Considering Gause's law, conduct research on the California Red Legged Frog and the Northern Pacific TreeFrog (use wiki or other google search). Create a chart that compares the two with regard to their niche or their lifestyle that may explain how these two native frogs have evolved to coexist in the same ecosystem.

Both hawks and owls feed on small mammals to sustain their respective populations without causing competitive exclusion. How can this work when both species live in the same geographic area?
A predators can feed on several prey species, but prefer to attack those with the weakest defenses. The same predator may shift to a different prey species that becomes more common or more easily overcome when the previousiy preferred prey had acquired better defenses against the predator. This shifting strategy, known as _____________, results in sequential or alternating bouts of pairwise coevolution between many different species. A. resource shifting B. coevolutionary alternation C. ecological character displacement D. cospeciation
The principle of competitve exclusion states thata) Competition between two species always causes extinction or emigration of one species.b) Two species will stop reproducing until one species leaves the habitat.c) Two species cannot coexist in the same habitat. d) Two species that have exactly the same niche cannot coexist in a community.
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.
