HELP!! Seasonal variations in ocean temperatures can impact the populations of living organisms in the ocean. How would a phytoplankton population be affected by these changes?

Answer:
Increased sunlight and increased nutrients will increase phytoplankton populations
Explanation:
The phytoplankton is a producer. This means that it is able to produce its own sugars, or rather its own food, by using its environment. In order to do so, the phytoplankton performs the process of photosynthesis, and in order for this process to be performed, the phytoplankton needs sunlight. Increased sunlight will mean that the phytoplankton will be able to perform photosynthesis more frequently and more efficiently, which will result in increase of its population. Also, the nutrients play a role in the population of phytoplankton, as they provide crucial elements that are needed for the photosynthesis process, so the phytoplankton gets what it needs from them, so the more nutrients there are, the more phytoplankton there will be.
