A niche is a role or job played by an animals or organism in the wild. An animal that survives on their niche is a coyotes. They can adapt their niche quickly so they can live in many habitats. Another animal that survives on their niches is an aye-aye. The aye-aye uses their muddle finger to tap on trees to see if there’s any bugs in the tree, if there is they dig the bugs out with the middle finger. So the aye-aye survives on its niche because that’s how it gets food.
