(1) Sunderbans and Rann of Kutch

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.

In India, we find mangoes with different flavours, colours, fibre content, sugar content and even shelf-life. The large variation is on account of  

(1)  species diversity    

(2)  induced mutations    

(3)  genetic diversity    

(4)  hybridisation.
