What term refers to a species that no longer exists?

Explanation:
Extinction means a species has no living individuals anywhere on Earth. When a species is extinct, its lineage is gone and recovery through natural reproduction isn’t possible. Endangered describes species that are still alive but at very high risk of disappearing in the wild. Biodiversity refers to the variety of living things in an area or on Earth, not the survival status of a single species. Disruption is a disturbance to an ecosystem, not a label for a species’ survival status.
