Question

1. which of the following describes biodiversity hotspots?

a. regions with low levels of species diversity
b. areas rich in unique species at risk of destruction
c. locations dominated by invasive species only
d. places where no conservation is necessary

Explanation:

To determine the correct description of biodiversity hotspots, we analyze each option:

• Option a: Biodiversity hotspots have high, not low, species diversity, so this is incorrect.
• Option b: Biodiversity hotspots are defined as areas with a high number of unique (endemic) species that are also under threat of habitat destruction or other forms of damage. This matches the definition.
• Option c: Biodiversity hotspots are not dominated by invasive species; they have native, unique species. Invasive species are a threat to biodiversity hotspots, so this is incorrect.
• Option d: Biodiversity hotspots are in need of conservation due to the risk to their unique species, so this is incorrect.

Answer:

b. Areas rich in unique species at risk of destruction
