Q5.9. As you saw in Section 2 ("DO or Die"), fish are sometimes lost from lakes as eutrophication occurs. Given what you've learned in this lab about why these fish kills occur, which of the following might help prevent fish kills as phosphorus concentrations increase? Installing aerators that increase the oxygen concentration in the water Periodically adding more algae to the lake throughout the year Adding nitrogen to promote increased algal growth in the lake Trawling the lake with specialized nets to filter out extra zooplankton
