5.1 Ecоlоgy is the study оf orgаnisms in their environment. 5.1.1 Stаte whаt is meant by the term ecosystem. (1) 5.1.2 State what is meant by the term population. (1) 5.1.3 State what is meant by the term community. (1) 5.2 Which of these is an abiotic factor? Write down the correct answers A, B , C or D. A. availability of mates B. number of pathogens C. number of predators D. acidity of soil (1) 5.3 The diagram (Figure 5.3 addendum) shows the nitrogen cycle with four processes labelled A, B, C and D. 5.3.1 Which process is nitrogen fixation? (1) 5.3.2 Which process is decomposition? (1) 5.3.3 Which process is nitrification? (1) 5.4 Explain how nitrate can help the plants grow. (1) 5.5 Many animals excrete urine that contains urea. 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)
