Question

Which one is a hotspot for biodiversity?
A. Aravalli hills
B. Western ghats
C. Indo gangetic plains
D. Eastern ghats

Answer 1

Hint: The biodiversity is the combined diversity of all levels of biological organization. The loss of biodiversity is more happening these days. Therefore, the government planned several programs for the conservation of biodiversity.

Step by step answer:Conservation of biodiversity is done in two ways. They are in-situ conservation and ex-situ conservation. In in-situ conservation species are conserved in their natural habitat. It differs from ex-situ conservation as in this type, endangered species are preserved outside their natural place of living. Under in-situ conservation, we have built biosphere reserves, natural parks, and wildlife centuries. Through these ways, we protect endangered species in their natural habitat without interfering with their living. Endemic species are the kind of species that are seen only in a particular area. Based on the number of endemic species, we have created many biodiversity hotspots all around the globe. Know that in total there are 34 biodiversity hotspots. These regions are characterized by a high level of species richness and also an alarming level of accelerated habitat loss. Among the 34 biodiversity hotspots, three of them are located in India. They are western ghats and Sri Lanka, Indo-Burma, and Eastern Himalayas. Note that even the biodiversity hotspots cover less than two percent of the world's total land area, by protecting these regions we can decrease the rate of species extinctions by 30%.
Hence, the correct option is B.

Note: Botanical Gardens, zoological parks, wildlife safari parks, etc are examples of ex-situ conservation in which organisms are taken out from their natural habitat and protected in a man made environment. The development of technology enables us to preserve endangered species by methods like tissue culture, cryopreservation, etc.
