Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In Red data book, on the basis of the degree of threat, 9 categories have been given.

Species are classified by the IUCN Red List into nine groups, set through criteria such as rate of decline, population size, the area of geographic distribution, and degree of population and distribution fragmentation.

  1. Extinct (EX) – No known individuals remaining.
  2. Extinct in the wild (EW) – Known only to survive in captivity, or as a naturalized population outside its historic range.
  3. Critically endangered (CR) – Extremely high risk of extinction in the wild.
  4. Endangered (EN) – High risk of extinction in the wild.
  5. Vulnerable (VU) – High risk of endangerment in the wild.
  6. Near threatened (NT) – Likely to become endangered in the near future.
  7. Least concern (LC) – Lowest risk. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
  8. Data deficient (DD) – Not enough data to make an assessment of its risk of extinction.
  9. Not evaluated (NE) – Has not yet been evaluated against the criteria.

When discussing the IUCN Red List, the official term "threatened" is a grouping of three categories: Critically Endangered, Endangered, and Vulnerable.

D Correct answer
Explanation

Red data book will provide information about endangered species. The Red Data Book was established for documenting rare and endangered species of animals, plants and other organisms. Species which are facing the high risk of extinction are called endangered species. Some of the endangered plants include Ebony tree, Umbrella tree, Indian mallow etc., and few of the endangered animals are Blackbuck, One Horned Rhinoceros, and Asiatic Lion etc.

Thus, the correct answer is option D.

C Correct answer
Explanation

The taxon likely to join the category of endangered category in near future is Vulnerable if the causal factors continue to operate. Vulnerable included all those taxa in which most or all population decrease in size because of over-exploitation, extensive destruction of habitat and other environmental disturbances. 

Therefore, the correct answer is option C.
