Answer :
The neritic zone is the most productive zone among the choices given. The correct option among all the options that are given in the question is the fourth option or the last option. This is the zone where the water is shallow and sunlight reaches the ocean floor. I hope the answer comes to your help.
Final answer:
The neritic zone is the most productive of the four zones mentioned due to its shallow depth, which allows sunlight to reach the bottom. This facilitates photosynthesis, leading to high nutrient availability and biodiversity.
Explanation:
Of the four zones mentioned, the neritic zone is by far the most productive. The neritic zone is the region of the ocean that extends from the low tide mark to the edge of the continental shelf, and is characterized by its relatively shallow depth. This shallow depth allows sunlight to reach the bottom, enabling photosynthesis by plant life and algae. As a result, there is a high level of nutrient availability and biodiversity, contributing to its high productivity. The intertidal zone, aphotic zone, and oceanic zone do not have the same combination of conditions, making them less productive overall.
