(D) In general,species diversity decreases as we move away from the equator towards the poles. The possible reasons are as follows:$(i)$ Temperature decreases as we move away from the equator towards the poles,which limits the metabolic activities of many organisms.$(ii)$ The intensity of sunlight decreases as we move away from the equator towards the poles,leading to lower primary productivity.$(iii)$ In polar regions,the temperature is extremely low,making it difficult for most organisms to survive in that habitat.
