  2. endangered species

  3. nearly threatened species

  4. rare species


Correct Option: C
Explanation:

  1. Blue-throated macaw

  2. Bald eagle

  3. Great Indian bustard

  4. Baikal teal

Which cause in the above mentioned passage is responsible for mass extinction

The four causes of extinction are:

1. Alteration of habitat
2. Hunting
3. Legal lapses
4. Nature of man

  1. Habitat alteration

  2. Hunting

  3. Legal lapses

  4. Nature of man


Correct Option: A
Explanation:

Habitat alteration is the main cause of massive depletion of wild life. Absence of cover or shelter, reduction in movement area and destruction of wild plants deprive the animals from shelter, protection and food, which lead to the death of a lot of animals in a very short period of time, resulting in mass extinction.

What is the criterion for categorising a species as vulnerable by IUCN?

  1. Likely to become endangered in the near future

  2. Extremely high risk of extinction in the wild

  3. High risk of extinction in the wild

  4. High risk of endangerment in the wild


Correct Option: D
Explanation:

A species which has high risk of endangerment in the wild is categorised as 'vulnerable' by IUCN.

Which wildlife sanctuary is a tiger reserve too?

  1. Kaziranga Wildlife Sanctuary

  1. Seed banks

  2. Shifting cultivation

  3. Gene banks

  4. Botanical gardens

What is the modern use of sacred groves?

  1. Repository for various Ayurvedic medicines

  2. Reduce soil erosion

  3. Biodiversity hotspots

  4. Recharging aquifers


Correct Option: C
Explanation:

In modern times, sacred groves have become biodiversity hotspots as various species seek refuge in the areas due to progressive habitat destruction and hunting. Sacred groves often contain plant and animal species that have become extinct in the neighbouring areas. They, therefore, harbour great genetic diversity.

Viable material of endangered species can be preserved by

  1. gene bank

  2. gene library

  3. gene pool

  4. gene map


Correct Option: A
Explanation:

Gene banks are a type of bio-repository, which preserve viable genetic material. For plants, this could be by freezing cuttings from the plant or stocking the seeds. For animals, this is freezing of sperms and eggs in zoological freezers until further need.
