E Correct answer
Explanation

IUCN is the 'International Union of Conservation of Nature and Natural Resources', which is not called as 'World Conservation Union' (WCU). It maintains a 'Red Data Book' Or 'Red List', which is a catalog of taxa facing the risk of extinction. The purpose of preparing the 'Red List' is to provide awareness to the degree of threat to biodiversity, provide global index about already declined biodiversity. Identification of species at greater risk of extinctions and preparing conservation priorities and help in conservation. 

Endangered species need to be noticed because only after that the planning for their protection and improving their population can be given the proper direction.

  4. 16,241
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The species (including animals, plants, fungi, etc.) which are vulnerable to endangerment in the near future are known as threatened species. The International Union for Conservation of Nature (IUCN) is the authority on threatened species, and it treats threatened species as a group of three categories, depending on the degree relative to which they are threatened. Those categories are Vulnerable species; Endangered species and Critically endangered species. As per the Red list of 2000, there are 11,096 threatened species.

So, the correct answer is '11,096'.

  1. Mammals

  2. Amphibians

  3. Reptiles

  4. Birds
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
According to the IUCN Red List, during the last two decades, the maximum increase in the number of threatened species is among amphibians as some groups like amphibians appear to be more vulnerable to extinction. More than 15,500 species worldwide are facing the threat of extinction. Presently, 12 percent of all bird species, 23 percent of all mammal species, 32 percent of all amphibian species and 31per cent of all gymnosperm species in the world face the threat of extinction.
So, the correct answer is 'Amphibians'.

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

The IUCN 'Red List of Threatened Species' is also known as the IUCN Red List or 'Red Data List'. It was founded in 1964, and it is the world's most comprehensive inventory of the global conservation status of biological species. The International Union for the Conservation of Nature (IUCN) is the world's main authority on the conservation status of species. 

A series of 'Regional Red Lists' are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. The aim is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to try to reduce species extinction.
