Question

There are many animals that have become extinct in the wild but continue to be maintained in zoological parks.
(a) What type of biodiversity conservation is observed in this case?
(b) Explain any other two-ways which help in this type to conservation.

Answer 1

(i)It is an example of ex-situ conservation. In this approach, threatened plants and animals are taken out of their natural habitat and placed in suitable settings and given special care.
(ii) Cryopreservation and tissue culture are two ways that help in ex-situ conservation. In cryopreservation, gametes of threatened species are preserved in viable and fertile conditions at subzero temperatures, which helps in preserving these cells for longer periods. In tissue culture, plants are propagated from a small mass of tissue called callus.
