Question

‘Biosphere reserve’ is an example of
A. In-vivo conservation
B. Ex-situ conservation
C. In-situ conservation
D. All of the above

Answer 1

Hint: There are two forms of biodiversity conservation, Ex-Situ conservation and In-Situ conservation. The term ‘In-situ’ originates from the Latin word, which means on-site, whereas the term ‘Ex-situ’ means off-site.

Complete answer:
Biosphere reserves are the natural sites which are reserves to study sustainable development. They are on-site conservation areas which ensure that the natural ecosystem of plants and animals do not get disturbed. Biosphere reserve shows the interaction between the ecosystem and social system. It helps in conserving biodiversity.
-In-situ conservation is the type of conservation in which animal and plant species are conserved in their natural habitat. The ecosystem and biodiversity are maintained and recovered.
-Examples of In-situ conservation are National park, wildlife sanctuary, and biosphere reserve.
-Ex-situ conservation is the type of conservation in which plant and animal species are protected away from their natural environment. This kind of conservation is mainly done to protect endangered species.
-Ex-situ conservation is done by removing the species from the threatened environment to a safe environment where humans take them to care. For example, botanical garden and zoological garden
-In-vivo conservation is a type of conservation in which a wide range of activities is adopted to ensure the survival of the species which are about to get extinct. For example, the pathogenesis of the disease is compared.

Hence, the correct answer is option (C).

Note: In in-situ conservation, the activities of the humans are either prevented or restricted to conserve them. This in-situ conservation helps in conserving many endemic species of the area. Ex Situ conservation means conservation outside the habitats by preserving the population of samples in genetic resource centers, such as botanical gardens, zoos, etc. or in the type of gene pools and gamete storage, seed germplasm banks, pollen, etc.
