In the northern hemisphere, when does the phytoplankton biomass peak in the polar region? why?
White raven [17]

Given what we know about phytoplankton biomass peaks in the polar region of the northern hemisphere, we can confirm that this occurs in the spring.

As the polar regions are tilted away from the sun, days there are short, sometimes these regions even enter month-long periods of darkness. Due to this, sunlight is not always strong enough to penetrate deep into the water.

In the Northern Hemisphere, the phytoplankton biomass peaks in the spring given that during this time the sun is high enough in the sky for sunlight to penetrate deep into the water and provide a food source for the plankton to thrive.

A basic factor on ones internal clock is sunlight. It controls the regulation of melatonin which aid in synchronizing cells in the body.

Specific cells of the tissue at retina moves the light signals the thypothalamus.

At night, the hypothalamus signal to the pineal gland to produce melatonin. At daylight hours, the reverse is the case.
