The species confined to a particular region and not found elsewhere is termed as

(1) keystone

(2) alien

(3) endemic

(4) rare

The following graph depicts changes in two populations (A and B) of herbivores in grassy field. A possible reason for these changes is that

1. both plant populations in this habitat decreased

2. population-B competed more successfully for food than population-A

3. population-A produced more offspring than population-B

4. population-A consumed the members of population-B

Cryopreservation of gametes of threatened species in viable and fertile condition can be referred to as

(1) in situ conservation of biodiversity

(2) advanced ex situ conservation of biodiversity

(3) in situ conservation by sacred groves

(4) in situ cryo-conservation of biodiversity

An example of ex situ conservation is 

1. National Park             

2. Seed Bank

3. Wildlife Sanctuary       

4. Sacred Grove

The organisation which publishes the Red List of species is

1. ICFRE  

2. IUCN  

3. UNEP  

4. WWF
