Question

question 1 (multiple choice worth 2 points)which statement best compares coastal ecosystems to open ocean ecosystems?coastal ecosystems include abyssopelagic depths, and open ocean ecosystems do not.coastal ecosystems have less sunlight, fewer nutrients, and less diversity than open ocean ecosystems.coastal ecosystems have a greater range of water pressures than open ocean ecosystems.coastal ecosystems have more sunlight, more nutrients, and higher levels of productivity than open ocean ecosystems.

Explanation:

Coastal ecosystems are shallow, so they receive more sunlight than the deep open ocean. They also get more nutrients from runoff from land, which supports higher productivity. Abyssopelagic depths are part of the open ocean, not coastal, so the first option is wrong. Coastal ecosystems have more sunlight, nutrients, and diversity than open ocean, so the second option is incorrect. Open ocean has a much greater range of water pressures (from surface to deep abyssal zones) than shallow coastal areas, so the third option is wrong.

Answer:

D. Coastal ecosystems have more sunlight, more nutrients, and higher levels of productivity than open ocean ecosystems.
