A species found in only one geographic location is described as:

• A. Native
• B. Endemic
• C. Cosmopolitan
• D. Invasive

Answer: (B)

When a species is found in only one geographic location, it is described as endemic. This term shows a very restricted distribution tied to a specific place, often because the species evolved there in isolation or depends on a unique local habitat. Endemic species are particularly vulnerable to local threats because there are no other populations elsewhere to rely on for survival or re-colonization. This is different from native, which means a species occurs naturally in an area but can also be found elsewhere; cosmopolitan, which refers to species that are widespread across many regions; and invasive, which describes non-native species that spread aggressively and disrupt local ecosystems. So, endemism specifically captures the idea of being confined to a single area.
