Describe the yearly productivity pattern in polar oceans, including the main factor that limits productivity in polar oceans.

Expert Solution

Step 1

Some polar regions like Arctic Ocean's Barents Sea experiences the continue darkness in winter for about three months and continuous illumination of the light during the summer for next three months. The diatom productivity increases mainly during the summer, when the sunlight penetrates into the deep waters. The diatoms create the favorable conditions for the growth of zooplankton. These are biomass, which will increase till October. This biomass provides food for variety of marine organisms.
