A sequence of the different stages that take place during eutrophication is shown below. 1 reduction in dissolved oxygen 2 increase in nitrate ions 3 death of organisms requiring dissolved oxygen 4 growth of producers 5 increased aerobic respiration by decomposers 6 death of producers followed by their decomposition What is the correct sequence in which these events happen during eutrophication?
- A1 2 3 2 5 2 2 2 6 2 4
- B2 2 4 2 1 2 6 2 5 2 3
- C2 2 4 2 6 2 5 2 1 2 3
- D5 2 1 2 3 2 6 2 2 2 4
