Which one of the following pairs of geographical areas show maximum biodiversity in our country?

(1) Sunderbans and Rann of Kutch

(2) Eastern Ghats and West Bengal

(3) Eastern Himalaya and Western Ghats

(4) Kerela and Punjab

Genetic diversity in agricultural crops is threatened by

(1) introduction of high yielding varieties

(2) intensive use of fertilizers

(3) extensive intercropping

(4) intensive use of biopesticides.

One of the ex situ conservation methods for endangered species is

(1)  wildlife sanctuaries

(2)  biosphere reserves

(3)  cryopreservation

(4)  national parks.

Keystone species deserve protection because these

(1)  are capable of surviving in harsh envinmental conditions

(2)  indicate presence of certain mineral in the soil

(3)  have become rare due to over exploitation

(4)  play an important role in supporting other species.

Biosphere reserves differ from National Parks and Wildlife sanctuaries because in the former
(1) human beings are not allowed to enter

(2) people are an integral part of the system

(3) plants are paid greater attention than the animals

(4) living organisms are brought from all over the world and preserved for posterity

Beta diversity is diversity

(1) in a community

(2) between communities

(3) in a mountain gradient

(4) on a plain

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 a large proportion of the biomass and which affects many other species.

Which of the following is best method of germplasm conservation ?

(1) Herbarium

(4) Zoological park

Which one has the largest species variety in India ?

(1) Wheat
