Answer: Western Ghats
Notes: A biodiversity hotspot is an area with unusual concentration of species, many of which are endemic. It is marked by serious threat to its biodiversity by humans. The concept was given in 1988 by Norman Myers. India shares its territories into three biodiversity hotspots viz. Eastern Himalaya, Western Ghats and Indo-Burma. Out of them, Eastern Himalaya and Western Ghats are mostly located within India’s territory. In the Indo-Burma Biodiversity hotspot, India shares only a small part in north East India. The Indo-Burma Biodiversity hotspot includes parts of northeastern India, Bangladesh and Malayasia
