In temperate oceans during the winter months:

Question

Quizplus · Accepted Answer

During the winter months in temperate oceans, there is typically an increase in nutrient concentrations due to cold water sinking and bringing nutrients up from deeper layers. At the same time, solar input decreases due to shorter days and lower sun angles. Water temperatures also tend to decrease due to cold air temperatures and reduced solar heating. Therefore, A (nutrient concentrations are high, solar input is low, and water temperatures decrease) is the best choice.
