Answer:
Option (2)
Explanation:
The earth is comprised of numerous species, and this diversification of species gradually increases from the polar region to the tropical region of earth. The tropical and equatorial region is comprised of different species as this region receives the maximum amount of energy, nutrients, sunlight and rainfall.
Some of the biologists often believe that the species diversity increases with the latitude. The higher latitudinal region are mostly covered with ice and glaciers. But without the occurrence of ice age in the past, there is still lesser but sufficient amount of energy that is available in the higher latitudinal region that can support different types of biome, comprising a significant number and variety of species.
Thus, the correct answer is option (2).
