Assertion: Conservation of biological diversity under natural conditions is in-situ conservation.
Reason: An increase in the number of Manipur deer from 17 to 150 in the zoos of Calcutta and Delhi is an example of this.The variety and variability of living organisms and ecosystems on this planet contributes to its biodiversity. Human interference in nature over the years has resulted in the rapid loss of biodiversity. Thus, there is a need to maintain this diversity as each of these organisms contribute greatly to the maintenance of equilibrium of various ecosystems in this planet.
On the basis of the approach used for conserving the biodiversity it has been divided into two strategies:
In-situ – Protection of organisms in their natural habitat, as seen in wildlife sanctuaries, national parks, biosphere reserves and sacred groves is known as in-situ conservation. Thus, assertion is a true statement.
Ex-situ - Protection of organisms by taking them away from their natural habitat and keeping them in controlled and well-protected environments is known as ex-situ conservation. Conservation of threatened or endangered animals in zoological parks is an ex situ approach towards saving them from extinction. There are many animals who have either become extinct or are on the verge of extinction in the wild but are being maintained in captivity in zoological parks. An increase in the number of Manipur deer from 17 to 150 in the zoos of Calcutta and Delhi is an example of such ex situ conservation. Thus, the reason is false
