Which one of the following species is confined to particular geographical area?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Endemic species
(1) Keystone species — Incorrect. A keystone species is one whose presence matters far more to its community than its numbers suggest. It is about its role, not about its area.
(2) Endemic species — Correct. Endemism means that a species is confined to one region and not found anywhere else. Such a species is an endemic species. Regions that have many endemic species are the biodiversity hotspots.
(3) Evolutionary species — Incorrect. This is not a term that tells where a species lives.
(4) Sympatric species — Incorrect. Sympatric species live in the same area as one another. This does not mean that they are found only in that area.
