Ex situ conservation includes:
Answer: D. zoological parks, botanical gardens, and seed banks and cryopreservation of gametes
Why: It protects species outside their natural habitat.
India has more than 50 000 genetically different strains of rice and 1000 varieties of mango. This is an example of:
Answer: C. genetic diversity within a species
Why: The medicinal plant Rauwolfia vomitoria varies in the potency of reserpine in different regions.
The dodo became extinct in the last 500 years. It was a native of:
Answer: B. Mauritius
Why: The Quagga was from Africa, the Thylacine from Australia and Steller's sea cow from Russia.
Setting aside an area as a biosphere reserve, with no removal of biological resources, is an example of:
Answer: A. in-situ conservation
Why: In-situ conservation protects species within their natural habitat, as in biosphere reserves, national parks and sanctuaries, unlike ex-situ methods such as zoos or seed banks.
The three levels of biodiversity are:
Answer: A. genetic, species and ecological diversity
Why: Each level is important in its own right.
Over-exploitation of a species was the reason for the extinction of:
Answer: D. Steller's sea cow and the passenger pigeon
Why: Many marine fish populations are also declining.
The three hotspots of India are:
Answer: D. the Western Ghats and Sri Lanka, Indo-Burma, and the Himalaya
Why: They have many endemic species.
Species diversity generally shows a latitudinal gradient of being:
Answer: B. highest near the equator, decreasing towards the poles
Why: Tropical regions near the equator support the greatest species richness, decreasing progressively towards temperate and polar latitudes.
