which of the following does not represent biodiversity of a geographical region

Dear student,

Environmentalists have declared certain regions as ‘‘hot spots’’ for maximum protection of the regions which have high levels of species richness  and  high degree of endemism.  Many critical biodiversity hotspots are located in islands, tropical rain forests, and coastal areas. So Endangered species and diversity in organisms living in region does not account for biodiversity of region. Option b is correct.
Example, Western Ghats and Sri Lanka and Himalayas.
