Why is it that two species Cannot occupy the same niche for an extended of time?
The competitive exclusion principle tells us that two species can’t have exactly the same niche in a habitat and stably coexist. That’s because species with identical niches also have identical needs, which means they would compete for precisely the same resources.
What prevents two species from inhabiting the same niche at the same time?
a) The competitive exclusion principle, also called Gause’s Principle, states that when two species compete for exactly the same resources (thus, they occupy the same niche), one is likely to be more successful. As a result, one species “outcompetes” the other species, and eventually the second species is eliminated.
What happens if two species attempt to occupy the same niche?
If two species attempt to occupy the same niche, one species will be better at competing for limited resources and will eventually exclude the other species. The resources utilized by these species are similar yet different. Therefore, each species has its own niche and competition is minimized.
Is it an advantage for two species to share the same niche?
If two species do fill the same niche, they will compete for all necessary resources. One species will out compete the other, forcing the other species to adapt or risk extinction. This is known as competitive exclusion.
How many species can occupy a niche?
The description of a niche may include descriptions of the organism’s life history, habitat, and place in the food chain. According to the competitive exclusion principle, no two species can occupy the same niche in the same environment for a long time.

Can an organism’s niche change?
The ‘fundamental’ niche is that defined by the requirements of the organism. The realized niche will therefore change constantly depending on the changes in abiotic and biotic factors.

Why don t most species occupy their entire fundamental niches?
In nature, however, many species do not occupy all the habitats permitted by their anatomy and physiology. That is because other species compete for available resources, prey on the organisms in question, or influence their growth and reproduction, reducing the range actually occupied
Why is it important to test values outside of the realized niche?

Which is the best definition of a realized niche?
