Solution
In general, species diversity decreases as we move away from the equator toward the poles.
The possible reason could be as follows:
- Temperature decreases as we move away from the equator towards the poles.
- The intensity of sunlight decreases as we move away from the equator towards the poles and hence productivity.
- In polar regions, the temperature is very low so most of the organisms cannot survive in that habitat.
