Which zone is the most productive? intertidal zone aphotic zone oceanic zone neritic zone

Answers

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.

According to the article titled “Can Korea Be Reunited,” what is the biggest obstacle to the unification of North and South Korea?

Answers

I have not read about the said article but maybe this can be of help. One of the biggest challenge for the unification of North and South Korea would be the  incompatibility of governments between the North and South. The two are polar opposites. Hope this helps. Have a nice day.

Answer:

The main obstacles are the strained relations between North Korea and other countries apart from South Korea, including the United States & China

Explanation:

The main obstacles are the strained relations between North Korea and other countries apart from South Korea, including the United States & China. The major sticking point is that the U.S. and North Korea are in a military conflict legally, meaning that the termination of Korean War was only a ceasefire they never really addressed all the problems of that war formally. And that's why U.s. forces are still in South Korea, and this is why they are all on armed alert pretty much, they can combat at any moment.
