Explain, giving three reasons, why tropics show greatest levels of species diversity.

उत्तर
The tropics exhibit the greatest levels of species diversity for these reasons:
- High solar energy: As there is more food available in tropical areas, which receive more solar radiation, productivity and biodiversity are higher.
- Stable climate: In the tropics, less seasonal change encourages niche specialisation, which makes it possible for more species to coexist.
- Evolutionary history: As tropical places have not been significantly impacted by glaciation, organisms have had more time to evolve and diversify.

Tropical regions exhibit species richness as compared to polar regions. Justify.
Maximum species richness is observed in the ______.

Select the correct alternative for x and y.
A species-area curve is drawn by plotting the number of species against the area. How is it that when a very large area is considered the slope is steeper than that for smaller areas?
Is it true that there is more solar energy available in the tropics? Explain briefly.
