Hotspots of Biodiversity - Unsolved Practice Set

Q1. A biodiversity hotspot is defined as a region that shows:

1. Low species richness and no threat of habitat loss
2. Exceptionally high species richness and endemism, combined with significant threat of habitat loss
3. Only high species richness, with no consideration of threat level
4. Complete absence of any human impact

Q2. Endemism, an important criterion for identifying biodiversity hotspots, refers to:

1. Species found only in one particular, restricted geographic region and nowhere else
2. Species found in every region of the world equally
3. Species that have gone extinct
4. Species introduced artificially into a new region

Q3. Which of the following biodiversity hotspots is located within India?

1. The Amazon Basin
2. The Western Ghats-Sri Lanka hotspot
3. The Sahara Desert
4. The Arctic tundra

Q4. Biodiversity hotspots are considered important for conservation planning mainly because they help:

1. Identify regions with the least conservation priority
2. Prioritise limited conservation resources toward areas with the highest combination of species richness, endemism, and threat level
3. Justify the complete exploitation of natural resources
4. Eliminate the need for any conservation efforts elsewhere

Q5. Besides the Western Ghats-Sri Lanka hotspot, which other major biodiversity hotspot region is found within or bordering India?

1. The Galapagos Islands
2. The Himalaya
3. The Great Barrier Reef 
4. The Congo Basin
