Quizplus · Accepted Answer

The vertical movement of cold water in oceans brings nutrient-rich water to the surface, which in turn enhances primary productivity and supports the growth of surface organisms such as phytoplankton and zooplankton. These organisms provide food and oxygen for higher trophic levels, including fish and marine mammals. Thus, the vertical movement of cold water plays a critical role in the functioning of the oceanic ecosystem and its food web.
