When two organisms fill the same niche, competition for resources will intensify. This can lead to one species outcompeting the other, resource partitioning where each species utilizes different resources, or evolutionary changes in one or both species to reduce competition. Ultimately, it can result in one species displacing the other or both coexisting through niche differentiation.
If 2 mouse species tried to occupy the same niche they would fight. The mice fight to right to occupy the niche. The winner of the fight gets the niche.
The short answer is that one is always going to be slightly better at that exact niche than the other, and so will drive the competitor to local extinction. In reality, two species in nearly the same niche will often co-occur, but there will be more resources in a very similar niche that will allow for one species to exploit those other resources. Evolution can happen very quickly in these high competition areas (in a matter of a few years, it has been directly measured).
species that have very similar resource requirements and niche preferences, leading to direct competition for limited resources, ultimately resulting in the elimination or exclusion of one species by the other.
In theory, multiple organisms can occupy the same niche through resource partitioning, where each species uses different resources or occupies a different part of the niche. However, intense competition may limit the number of species that can coexist in a specific niche in reality.
According to the competitive exclusion principle, two species cannot continue to occupy the same ecological niche in a community because one will outcompete the other leading to the elimination of the less adapted species.
some do. You can find a similar placental mammal for every marsupial animal. Example: Kangaroos fill the same niche as North American deer. etc.
Ecological Niches are much more specific than 'Mammal'. For instance, Bears fill the top predator niche in lots of alpine forest regions; while mice fill a seed-eating small-creature niche in the same ecosystem.
no they do not have the same niche but same habitat, so what?
Yes they do have the same niche
No..
no, very similar genetic information. as you and i dont have the same genetic information do we? same ecological niche? well sorta, i wouldnt call it an ecological niche, the factors that make the niche such as temperature, humidity, host range would be the same.

Because depending on where the organism is located, then there it will develop its niche.

no!
well
