In which region biodiversity is richer?

Answer : Option (A) is correct because biodiversity is richer in tropical regions. Tropical forest ecosystems cover less than 10 percent of earth’s surface, and contain about 90% of the world’s species.

Which of the following region is more rich in species?

Tropical rainforests are the richest habitat of all, tropical grasslands exhibit more diversity than temperate grasslands, and deserts in tropical or subtropical regions are populated by a wider range of species than are temperate deserts.

Which of these regions are rich in biodiversity tropical regions polar regions temperate regions oceans?

Answer: The richness of the biodiversity mainly depends upon the temperature and sunlight that falls. Explanation: Now at the tropical areas of the world, we have most of the forests and the highest number of the species richness.

To qualify as a biodiversity hotspot, an area must meet two strict criteria: Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as “endemic” species). Have lost at least 70 percent of its primary native vegetation.

Why species diversity is high in equatorial regions?

A new study led by Oxford Earth Sciences’ Associate Professor Erin Saupe suggests that higher species diversity in equatorial regions may be caused by higher rates of speciation (the formation of new and distinct species in the course of evolution), driven by changes in precipitation across space and through time.
