2. Waters in the coastal ocean tend to be more productive than waters of similar depth in the
open ocean. What is the main reason for the productivity difference?
(A) more sunlight
(B) warmer temperatures
(C) nutrient-rich runoff from the land
(D) higher levels of dissolved carbon dioxide



Answer :

Final answer:

The main reason for higher productivity in coastal ocean waters compared to open ocean waters is the nutrient-rich runoff from the land.


Explanation:

The main reason for the productivity difference between coastal ocean waters and open ocean waters is the nutrient-rich runoff from the land. Coastal waters receive a high abundance of nutrients from runoff, streams, and rivers that empty into the ocean, stimulating production. Additionally, the shallower bottom along the continental shelf traps nutrients in coastal waters and prevents them from sinking to greater depths, leading to increased productivity.
