Species diversity decreases from equator to poles. The reason lies behind the fact that the conditions for the survival of species at poles become unfavorable. The Equator has favorable conditions for the survival of wildlife. Good vegetation, sunlight, and habitat these factors are responsible for great biodiversity at the equator.
So, the correct answer is 'Species diversity increases from equator to poles'.
