Explanation: 

Detailed explanation-1: -Endemic species are those species which are found in one particular place on the planet. They are not found anywhere else. Endemic species run a higher risk of extinction because of their geographic isolation.

Detailed explanation-2: -Endemism is a term used in biology to talk about the distribution of a taxon limited to a small geographic area and which can therefore be found naturally in this place. In consequence, endemic species are those that live in a limited area, such as a mountain range, lake or island, among others.

Detailed explanation-3: -Species that are confined to some particular areas usually isolated by geographical barriers are known as Endemic Species.

Detailed explanation-4: -Often an endemic species is confined to a certain area because they are highly adapted to the particular niche. They may eat only a certain type of plant that is found nowhere, or a plant is perfectly adapted to flourish in a very particular climate and soil type.

Detailed explanation-5: -There are two types of endemism-paleoendemism and neoendemism. Paleoendemism means that a species used to live in a large area but now lives only in a smaller area.
