In Marine Ecosystems, Net Primary Productivity Tends to Be

Question

In marine ecosystems, net primary productivity tends to be
A)greater along shorelines where terrestrial nutrients enter the marine environment.
B)lower where the oceans border land because terrestrial pollution suppresses marine productivity.
C)lowest in areas where upwelling brings colder water to the surface.
D)greater than the net primary productivity on land.

Accepted Answer

Terrestrial nutrients, such as from rivers, enhance productivity in coastal areas, leading to higher net primary productivity. Upwelling can also bring nutrients to the surface, increasing productivity in those areas. However, overall productivity in marine ecosystems is generally lower than that of terrestrial ecosystems.
