Some soil microorganisms use the enzyme urease to change urea to ammonium ions and carbon dioxide. Describe how ammonium ions can be converted to nitrate ions in the soil. (2) 5.6 Describe the process of eutrophication and the effect it will have on the environment. (4) 5.7 Nitrates are one cause of pollution in rivers. The graphs show the changes in nitrate levels and the biological oxygen demand (BOD) of the same rivers over a number of years. A high BOD means that there is a large population of microorganisms in a water sample. (see addendum for figure 5.7) 5.7.1 Describe how the nitrate levels and BOD change over the time period shown. (2) 5.7.2 Explain the relationship between nitrate levels and BOD in these rivers. (4)
