NPP is generally lower at 25° latitude than it is 10° closer to the equator or 10° closer to the poles. What is the best explanation for this phenomenon?
A) Descending Hadley cells disrupt the ability of plants to acquire carbon dioxide.
B) It is much drier at this latitude.
C) This latitude corresponds with high concentrations of upwelling zones.
D) Decomposition rates are particularly high at this latitude.
