Hint: In-situ approach includes the protection of a group of typical ecosystems through a network of protected areas, which are areas of land and /or sea, specially dedicated to the protection and maintenance of biological diversity. In ex-situ, there is conservation outside their habitats by perpetuating sample populations at different places.
Complete answer:
• Biosphere reserve: These are a special category of protected areas of land and /or coastal environments. Each biosphere reserve has a Natural or core zone (where no human activity is allowed), a buffer zone (where limited human activity), and a transition zone (where human activity is allowed without degradation of ecology).
• Gene bank: DNA of endangered species is conserved in museums, zoos, or herbaria. Their collection of living materials in the form of zoo animals, botanical collections, and seeds, together with DNA collections have been termed gene banks.
• Cryopreservation: It is a method of storage of material at a very low temperature (especially in liquid nitrogen at -196C).
• Botanical garden: Conservation of biodiversity in botanical gardens. There are more than 1500 botanical gardens in the world.
• Sacred forests and sacred Lakes: These are protected by tribal communities due to religious sanctity according to them.
Hence, the correct answer is option (A).
Note: Ex-situ includes gene bank, cryopreservation, and botanical garden, zoo. Whereas In-situ includes sacred grooves, biosphere reserve, national parks.
There are 13 biosphere reserves in India and tourism here is normally not permissible.
In gene banks, they provide the potential to breed the species in captivity and to release it when the conditions are more favourable.
