Question

The taxa believed likely to join the endangered category in near future is called :
A. Rare
B. Extinct
C. Vulnerable
D. Living fossil

Answer 1

Hint: Any species that is at risk of going extinct in the near future is considered a threatened species. Depending on how seriously they are threatened, threatened species are divided into three categories by the International Union for Conservation of Nature: vulnerable, endangered, and severely endangered.

Complete step by step solution:
Critically Endangered Species
The IUCN's highest risk category for wild species is Critically Endangered (Cr). A species' populations have declined or would decrease by 80% within three generations if it is classified as critically endangered. Its chances of going extinct in the wild are therefore thought to be exceedingly high.

Endangered (EN) species
A population of organisms classified as an endangered species (EN) is in danger of going extinct because it is either rare or threatened by shifting environmental or predation factors. Additionally, it can imply that there may be a shortage of food or water as a result of deforestation. As a result, it is thought to be at extremely high risk of going extinct in the wild.

Threatened (VU) species
The IUCN has classified some species as vulnerable (VU) species, meaning they are at risk of going extinct unless the conditions affecting their survival and reproduction change. As a result, it is thought to be at very high risk of going extinct in the wild.

A vulnerable species is an animal or plant that is at risk of going extinct unless anything is done to stop it. The things that are detrimental to their survival must be removed, and they must reproduce at a higher pace. The IUCN "Red List" has 8,565 species that are classified as vulnerable.

Therefore option C is the correct answer, Vulnerable.

Note:
When the final member of an extinct species passes away, the species is declared extinct. When there are no living creatures left that can reproduce and pass on a new generation, extinction becomes inevitable.
When just a small number of individuals remain and are incapable of procreating due to ill health, old age, sparse distribution over a vast range, a lack of members of both sexes (in sexually reproducing species), or other factors, a species may become functionally extinct.
