What is so special about tropics that account for their greater biological diversity? Tick the appropriate option.

• Tropics had glaciation in the past and cyclones in the present, that helps in species richness

• Tropics receive less sunlight when compared to poles, biological diversity becomes more in less sunlit areas.

• There is more solar energy in the tropics, contributing to more productivity and hence greater biological diversity.

Alexander Von Humboldt observed that within a region species richness increased with increasing __________but only up to a limit.

• Area

• Food

• Predators
