Nutrients supplied by runoff from the land

Explanation:

Coastal ocean refers to water under tidal influence and it is the point of connection between lands and ocean.

Forest and coral reefs tend to be more productive than waters of similar depths because deep water brought in by the surface is always rich in nutrients that support plants growth. Coastal upwelling supports the growths of coral reefs.
