Question

Coral reefs and kelp forests are found in the coastal ocean. why is the coastal ocean most productive than the open ocean?A. Low water salinityB. Clarity of the waterC. Warmer ocean temperaturesD. Land runoff provides a source of nutrients

Answer 1

The correct answer is the letter D. Land runoff provides a source of nutrients

Coastal water is more productive than the open ocean because the runoff from land often has a high concentration of nutrients. This nutrients will be deposited directly to the coastal water; thus, this will stimulate production. The open ocean is way deeper than the coastal water, so it is harder to stimulate nutrients.
