Biodiversity hotspots: Select one: a. house only 10% of all species of vascular plants. b. are home to nearly 20% of the world's population. c. are all located in tropical regions. d. contain few endemic species. e. all of these choices are correct

B. Home to nearly 20% of the world's population.

Explanation:

According to Myers edition of hotspot maps, it must contain at least 0.5% or 1,500 species of vascular plants as endemics, and it has to have lost at least 70% of its primary vegetation. Biodiversity hotspots host their diverse ecosystems on just about 2.4% of the planet's surface.

In summary, biodiversity hotspot is defined as a biogeographic region that is a significant reservoir of biodiversity. The term biodiversity hotspot specifically refers to 25 biologically rich areas around the world that have lost at least 70% of their original habitat. It was estimated in 1995 that more than 1.1 billion people, nearly 20% of world population, were living within the hotspots, an area covering about 12% of Earth's terrestrial surface.
