Answer 1

Answer: Sudden loss of habitat

Explanation:

Endangered species are animal or plant species that are in danger of going extinct.

This usually results from them suddenly losing their habitat and thus being exposed to unfamiliar conditions or threats that could end their existence. For instance, elephants losing their forest habitats in India and thus encroaching on farmland only to get shot for damaging farms.
