John is completing an internship in biology at the Clearwater Marine Aquarium. While interning there, he monitors an outdoor phytoplankton exhibit to observe how populations of phytoplankton change when exposed to light. It is observed that each year the phytoplankton population within the exhibit increases when it was exposed to high amounts of sunlight. A new apartment complex that overlooks the aquarium is being built. The phytoplankton that were receiving 8-12 hours of sunlight each day will now have between 2-5 hours of sunlight. How will the phytoplankton be affected by the new apartment building?
