  1. Western GhatsCevap
  2. Nicobar IslandsCevap
  3. C
    Gangetic Plain
  4. D
    Thar Desert

Cevap

The Western Ghats and the Nicobar Islands are both officially included within global biodiversity hotspots in India.
The Western Ghats and the Nicobar Islands are correct because India is home to four global biodiversity hotspots: Western Ghats, Himalayas, Indo-Burma, and Sundaland (which encompasses the Nicobar Islands). Both regions possess extreme levels of species endemism coupled with severe habitat destruction.

Adım Adım Çözüm

1
Identify the four global biodiversity hotspots associated with India.
The four regions are the Western Ghats (and Sri Lanka), the Eastern Himalayas (Himalaya hotspot), Indo-Burma, and Sundaland (which includes the Nicobar Islands).
Official conservation biology classification recognizes these specific zones based on species endemism and habitat threat levels.
2
Evaluate each choice against the recognized Indian biodiversity hotspots.
The Western Ghats forms its own hotspot region, and the Nicobar Islands fall under the Sundaland hotspot. The Gangetic Plain and Thar Desert are not designated hotspots.
Hotspots require at least 1,500 endemic vascular plant species and at least 70% loss of primary vegetation, criteria not met by major agricultural plains or arid desert belts.
