Worked practice questions
A biodiversity hotspot is a region with many endemic species that has also suffered what?
- Great habitat loss
- Frequent flooding
- Rapid urban growth
- Frequent earthquakes
Show answer and solution
Correct answer: A. Great habitat loss
Hotspots combine high endemism with serious habitat loss, which makes them conservation priorities.
Where are most biodiversity hotspots located?
- Polar ice deserts
- Deep ocean trenches
- Tropical forest areas
- Temperate steppes
Show answer and solution
Correct answer: C. Tropical forest areas
Most hotspots are forest areas, and most lie in the tropics.
