What Do Extinct and Endangered Mean?
Extinct: A species that no longer exists; all known individuals have died, ending its lineage. Example: the dodo bird.
Endangered: A species at risk of extinction due to dangerously low population numbers. Threats include habitat loss, poaching, climate change, and invasive species. Examples: giant panda, African elephant, black rhinoceros.
In short, extinct species are gone, while endangered species face a high risk of disappearing. Both terms highlight the need for conservation to protect biodiversity.
