Upwellings provide an important mixing mechanism for surface and deep waters that:
 
  a) bring high levels of oxygen to the seafloor
  b) brings cold, deep, highly saline nutrient-rich water to the surface
  c) brings cold, shallow, nutrient-poor water to the deep
  d) all of the above

Question 2

On rocky shores, different elevations have bands of different types of organisms. Why?
 
  a) because water temperature fluctuations are greater in the air than in the water, organisms that can stand greater temperature swings are found farther up the shoreline.
  b) as one goes farther up on the shoreline, nutrient levels increase, so different organisms respond to different nutrient levels.
  c) organisms are adapted to different levels of wave energy, which varies with elevation.
  d) organisms are adapted to different levels of sunlight, which varies with elevation.
  e) organisms are adapted to different levels of exposure to air and dessication, which are controlled by elevation.
