The open ocean is more productive in the polar zones than in the equator due to less disturbance to the organisms.
<h3>Why is the open ocean more productive in the polar zones than in the equator?</h3>
In the open seas, heavy winds and deep waters lead to a high turnover in the water column that prevents photosynthetic microorganisms from converting sunlight into energy while on the other hand, there is less disturbance on the polar zones which leads to higher productivity.
So we can conclude that the open ocean is more productive in the polar zones than in the equator due to less disturbance to the organisms.
