<span><span>The above statement is false. Compared to deep ocean water, water in the surface has the lesser supply of rich inorganic nutrients. But due to upwelling, </span>the absolute concentration of nutrients in the surface will be higher.</span>
<span>Upwelling brings those lost/sunk nutrients, plankton and carcasses to the surface. The surface then becomes feeding grounds for fish and other ocean life. </span>
