Explanation
Species that face a clear danger of extinction, and whose population and habitat have declined to such an extent that they may become extinct in the future, are called threatened or endangered species. • Vulnerable – Species that are at risk, but the threat is not considered as immediate or as severe as in the “Endangered” category. • Rare – Species whose numbers are low, but which are not yet considered to be directly on the verge of extinction. • Extinct – Those Species for which no living individual is found in natural habital.
