Biodiversity hotspots are typically characterized by...

• A. A small area with exceptionally high species richness
• B. Large areas with moderate species numbers
• C. Islands with no species
• D. Regions with minimal ecological value

Answer: (A)

Hotspots focus on places where a small area harbors a very large number of species, including many that are unique to that location. The idea is that a compact region can contain a surprisingly high diversity, making it especially important to protect. So the statement that describes a small area with exceptionally high species richness is the best fit. The other descriptions don’t match because they imply large regions with only moderate diversity, or places with no species at all, or areas of little ecological value, none of which capture the concentrated biodiversity and conservation importance of hotspots.
