Detailed explanation-1: -Different species can coexist in the same habitat, but competition is reduced when they occupy different niches. Changes in habitat, climate change, invasive species, overexploitation, and pollution are all significant direct drivers.

Detailed explanation-2: -The niche concept Is that the only way to define a niche? As we’ll see, two organisms with exactly the same niche can’t survive in the same habitat (because they compete for exactly the same resources, so one will drive the other to extinction). However, species whose niches only partly overlap may be able to coexist.

Detailed explanation-3: -No two species can have the exact same niche, otherwise they would be in direct competition for resources with one another. If this occurs, then one species will outcompete the other. If the losing species then does not adapt, it would lead to its extinction.

Detailed explanation-4: -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.

Detailed explanation-5: -A habitat is the place where an organism lives while a niche is that organism’s role within that environment. Habitat focuses on how the environment impacts the organism while nich focuses on how the organism impacts the environment.
