Why is upwelling such an important factor in creating areas of high biologic productivity?
 
  a) Upwelling brings nutrient-rich deep water to the surface where productivity is limited by the availability of nutrients.
  b) Upwelling delivers oxygen-rich water to the surface where productivity is limited by oxygen content in the water.
  c) Upwelling brings cool deep waters to the surface where productivity is limited by high temperature.
  d) Upwelling brings new phytoplankton to the surface where they can multiply rapidly.
  e) Upwelling causes rain, which results in less salty surface waters that are better suited for primary productivity.
