Species diversity decreases as we move away from the equator towards the poles. What could be the possible reasons ?

Consider the following statements with respect to patterns of biodiversity . A. With very few exceptions, tropics (Iatitudinal range of 23.5^(@)N to 23.5^(@) S ) harbour more species than temperate or polar areas. B. In general, species diversity increases as we move away from the equator towards the poles . C. The diversity of plants and animals is uniform throghout the world but shows a rather even distribution . D. The largely tropical Amazonian rain forest in South America has the greatest biodiversity on earth. Of the above statements :

Scientists estimate that species diversity decreases as we move away from equator towards the poles. Tropical Amazonian rainforest in South America has the greatest diversity on earth. Do you agree that there is something so special about tropics that might account for greater biodiversity. Justify your answer.
