4. meromictic lake with chemocline. how did the salinity layer move? did it mix with freshwater? would it take additional energy to mix both layers together, and if so, what sort of energy could enable mixing? is it possible to use the schmidt's equation to calculate the chemocline density? why or why not?

True the answer is true

Answer is b)eutrophication occurs when excess nutrients are present in aquatic ecosystems, resulting in the increased production of plant life and the subsequent decrease in the oxygen levels of the watereutrophication occurs when there are excess nutrients in a body of water. this results in plants having more food and reproducing  more, sometimes leading to more aquatic animal life as well. ultimately, this can reduce the oxygen level in the ecosystem.
