Question

Tropical regions harbour more species than the temperate regions. How have biologists tried to explain this in their own ways? Explain.

Hint:

The stability and resource availability in tropical regions make them biodiversity hotspots with numerous endemic species.

Answer 1

Biologists explain the higher species richness in tropical regions due to: Favourable climate: The warm and stable climate supports year-round plant growth and species survival. Longer evolutionary time: Tropical regions remained undisturbed during glaciation periods, providing longer periods for species diversification. Higher productivity: Abundant sunlight and rainfall result in high primary productivity, supporting diverse food webs.
