Nataly_w [17]

Answer:

E-You disagree because the resulting increase in phytoplankton at the surface would inhibit sunlight from penetrating into the water, thus inhibiting photosynthesis in the submerged plants.

Explanation:

Eutrophication is the process wherein nutrients specifically phosphorus and nitrogen are present in excess in a water body such as a lake. The increased concentration of nutrients promoter the growth of cyanobacteria and algae such as phytoplankton.

The increased population of phytoplankton in surface water reduces the oxygen availability and clarity of water for the organisms present in deeper layers.  Also, reduced clarity of water limits the amount of solar radiations penetrating the surface water to reach the deeper layers.

Increased nutrient levels of the lake would rather inhibit the growth of submerged plants due to reduced availability of sunlight as caused by presence of phytoplankton in surface water.
