8. How does the video describe hotspots in relation to other endangered areas?

a. They are like representatives for other endangered areas.

b. They are less important than other endangered areas.

c. They have fewer endemic species than other endangered areas.

d. They are independent units that protect biodiversity.

 

9. According to the video, why is it important to protect the highest number of species?

a. To enhance ecosystem stability and resilience.

b. To attract more funding for conservation efforts.

- True or False

1. Biodiversity hotspots are places on Earth that require special attention and protection.

2. It is possible to save the entire planet all at once.

3. The criteria used to determine biodiversity hotspots include the number of endemic plant species and the amount of lost habitat.

4. Animals are attracted to places where there are plants.

5. An endemic species is a species found in one specific area and nowhere else on earth.

6. If a species becomes extinct in a hotspot area, it can be replaced by similar species from other areas.

7. Less than three percent of the earth's land surface area is represented by biodiversity hotspots.

8. Hotspots are interconnected places on Earth and not just individual units.

9. The hotspot concept aims to protect the highest number of species, especially those that are most threatened.

10. Hotspots serve as a signal to enhance the stability and resilience of ecosystems.
