Why do tropical regions harbor significantly higher species diversity compared to temperate regions?

  1. Tropical latitudes were subjected to frequent glaciations in the past.
  2. Tropical environments are highly seasonal, unpredictable, and dynamic.
  3. Tropical regions received more solar energy and remained relatively undisturbed for millions of years.
  4. Tropical zones have smaller geographic area leading to concentrated speciation.

Correct answer · Option 3

Tropical regions received more solar energy and remained relatively undisturbed for millions of years.

Explanation

Tropical regions remained undisturbed for evolutionary diversification, are less seasonal/more constant, and receive more solar energy which contributes to higher productivity.
