Explanation:
Both sunlight and nutrients are required by phytoplankton communities. We know that <u>phytoplanktons</u> are <u>primary producers</u> and they produce food via <u>photosynthetic activities</u>. To carry out photosynthesis, <u>presence of (inorganic) nutrients and sunlight is highly important</u>. In this process, energy is fixed in energy rich molecules such as glucose and organism multiply and/or gain biomass. A decrease in any of them will result into reduced photosynthesis and hence reduced phytoplankton population growth.
