As big as it is, the ocean is nutrient-limited. If you wanted to investigate this, one reasonable avenue would be to
A)follow whale migrations in order to determine where most nutrients are.
B)observe Antarctic Ocean productivity from year to year to see if it changes.
C)experimentally enrich some areas of the ocean and compare their productivity to that of untreated areas.
D)compare nutrient concentrations between the photic zone and the benthic zone in various locations
E)contrast nutrient uptake by autotrophs in oceans of different temperatures.

Question

Quizplus · Accepted Answer

The best way to investigate the nutrient limitation in the ocean would be to experimentally enrich some areas of the ocean and compare their productivity to that of untreated areas. This would help in determining how much productivity is limited by nutrient availability in the ocean. The other options, such as observing whale migrations or contrasting nutrient uptake in oceans of different temperatures, may help in providing some data, but they may not be as effective in establishing the extent of nutrient limitation in the ocean.
