A rise in the concentration of nitrates in water may cause fish to die because of eutrophication. Some stages in eutrophication are shown below. 1 increased aerobic respiration by decomposers 2 increased decomposition after the death of producers 3 increased growth of producers 4 a decrease in dissolved oxygen What is the correct order of these stages leading to the death of fish?
- A$1 \rightarrow 4 \rightarrow 3 \rightarrow 2$
- B$1 \rightarrow 2 \rightarrow 4 \rightarrow 3$
- C$3 \rightarrow 2 \rightarrow 1 \rightarrow 4$
- D$3 \rightarrow 4 \rightarrow 2 \rightarrow 1$
