Correct Option: A
Explanation:

The IUCN - the International Union for the conservation of Nature & Natural resources maintains Red Data Book. The International Union for Conservation of Nature (IUCN) is an international organization which works in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, lobbying and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable."

  4. 3

Show answer
Correct Option: A
Explanation:

Red Data Book listed about 11096 species in 2000. The Red Data Book is the state document established for documenting rare and endangered species of animals, plants and fungi as well as some local sub-species that exist within the territory of the state or country. This book provides central information for studies and monitoring programmes on rare and endangered species and their habits. 

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

  1. Nine

  2. Ten

  3. Six

  4. Five

Show answer
Correct Option: A
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.

Different species are classified into different threat categories in the

biology main natural resources classification of threatened species red data book methods of conservation

  1. Blue Data Book

  2. Yellow Data Book

  3. Black Data Book

  4. Red Data Book

Show answer
Correct Option: D
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. 

Red Data Book contains information about

biology main natural resources classification of threatened species red data book methods of conservation

  1. Red coloured insects

  2. Red coloured fishes

  3. Red eyed birds

  4. Endangered plants and animals

Show answer
Correct Option: D
Explanation:

'Red Data Book' enlists the rare and endangered species of animals, plants and fungi, as well as some local subspecies. The book provides a central information source in organizing studies and monitoring programs on rare and endangered species and their habitats. It is regularly consulted when developing and implementing special measures for the protection and rehabilitation of such species.

The taxon likely to join the category of endangered category in near future is

biology main natural resources classification of threatened species red data book methods of conservation

  1. Extinct

  2. Rare

  3. Vulnerable

  4. Living fossil

Show answer
Correct Option: C
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.
