  1. Vulnerable

  2. Endanger

  3. Rare

  4. Extinct
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Endangered species is a species facing a high risk of extinction in the wild in the near future due to a decrease in its habitat, excessive predation or poaching.
Vulnerable species are those for which presently the population is sufficient but is undergoing depletion due to some factors so that it is facing the risk of extinction in a medium term.
Rare species are species with naturally small populations, either localized or thinly scattered.
Extinct species are the taxon completely eliminated or died out from Earth, e.g., Dodo.

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.
