Tо prоtect аn endаngered fish species, mаnagers have implemented new land management practices that have quickly and dramatically reduced nutrient lоading to Round Lake. As a result, the lake has shifted from eutrophic conditions to oligotrophic conditions. A. Identify which of these summer temperature profiles is from the lake in eutrophic conditions and which is from the lake in oligotrophic conditions. Letters represent different water layers. B. What are the names of the water layers (A, B and C) in profile 1? C. Which layer of water is likely to have the greatest concentration of dissolved nutrients at the end of the summer? D. Describe how the dissolved oxygen concentration will vary across the three water layers in profile 1. E. Do you expect to see a greater difference in dissolved oxygen concentration between the top and bottom layers when the lake is eutrophic or oligotrophic? F. This lake was able to recover quickly from eutrophication as external nutrient loading was reduced. Describe the process that could have prevented this quick recovery.
