A Marine Biologist Designs a Study to Measure Net Primary

question 72

Multiple Choice

A marine biologist designs a study to measure net primary productivity in the world's oceans.She travels to the coastal zone of each continent,takes measurements from north,south,east,and west points along the continent,and combines her data into a global average.Will these measurements be accurate?

• A)No, because ocean productivity is greatest past the intertidal zone.
• B)Yes, but only if she is sure to sample different climatic zones carefully, because production in different climatic zones may vary by an order of magnitude.
• C)No, because the continental edges have much higher productivities than the open ocean.
• D)No, because ocean life is greatest near the poles and decreases toward the equator.
• E)Yes, because although production in different climate zones differs, the open ocean is well mixed because of strong ocean circulation patterns.
