Q.

What is the full form of MAB in biology?

Q. Ginkgo biloba is no longer an endangered species because of its :

1. Ex-situ conservation
2. Off-site conservation
3. In - situ conservation
4. Cryopreservation

Q. "When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected."
This approach includes all of the following, except:

1. Biosphere reserves
2. Seed bank
3. National parks
4. Sanctuaries

Q.

What type of conservation is in-situ?

Q. Biosphere reserves differ from national parks because

1. they do not allow the entry of human beings
2. people are an integral part of the biosphere reserves
3. they focus more on the conservation of flora
4. they bring in living organisms from all over the world for conservation

Q. MAB is

1. Man and the Biosphere programme
2. Man and Botany
3. Man, Antibiotic and Bacteria
4. Man and Biotic community

Q. A biosphere reserve conserves and preserves

1. Wild animals
2. Land
3. Natural vegetation
4. All of the above

Q. How can you, as an individual, prevent the loss of biodiversity?

Q. What is a keystone species?

1. A species which makes up only a small proportion of the total biomass of a community, yet has a huge impact on the community's organization and survival.
2. A common species that has plenty of biomass, yet has a fairly low impact on the community's organization.
3. A rare species that has minimal impact on the biomass and on other species in the community.
4. A dominant species that constitutes a large proportion of the biomass and which affects many other species.

Q. Conservation in natural habitat is

1. in situ
2. ex situ
3. zoo
4. botanical garden

Q.

Give the full form of:
MAB

Q. Assertion :Pristine forests are among in-situ conservation strategies. Reason: These are sacred grooves where biota is protected on-site.

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
3. Assertion is correct but Reason is incorrect
4. Both Assertion and Reason are incorrect

1. Ex-situ conservation
2. Off-site conservation
3. In - situ conservation
4. Cryopreservation
