Alexander Von Humboldt described for the first time:
1. Laws of limiting factor
2. Species-Area relationships
3. Population Growth equations
4. Ecological Biodiversity
The species confined to a particular region and not found elsewhere are termed as:
| 1. | Keystone | 2. | Alien | 
| 3. | Endemic | 4. | Rare | 
In which of the following do both pairs have the correct combination?
| 1. | In situ conservation/National park  Ex-situ conservation/Botanical garden  | 
		
| 2. | In situ conservation/Cryopreservation  Ex-situ conservation/Wildlife sanctuary  | 
		
| 3. | In situ conservation/Seed bank  Ex-situ conservation/ National park  | 
		
| 4. | In situ conservation/Tissue culture  Ex-situ conservation/Sacred groves  | 
		
Cryopreservation of gametes of threatened species in viable and fertile conditions can be referred to as:
| 1. | Advanced ex-situ conservation of biodiversity | 
| 2. | In situ conservation by sacred groves | 
| 3. | In situ cryo-conservation of biodiversity | 
| 4. | In situ conservation of biodiversity | 
An example of ex-situ conservation is:
1. National park
2. Seed bank
3. Wildlife sanctuary
4. Sacred grove
A species facing extremely high risk of extinction in the immediate future is called:
1. Vulnerable
2. Endemic
3. Critically Endangered
4. Extinct
The organisation which publishes the Red List of species is:
| 1. | ICFRE | 2. | IUCN | 
| 3. | UNEP | 4. | WWF |
