When nitrates enter a lake, they trigger fast algae growth at the water’s surface. As a result, these changes happen in the lake: 1. the concentration of dissolved oxygen in the water decreases 2. fish and other aquatic animals die 3. decomposers increase their aerobic respiration 4. producers die and decomposition rises What is the correct sequence in which these changes take place?
- A$1 \rightarrow 2 \rightarrow 4 \rightarrow 3$
- B$3 \rightarrow 1 \rightarrow 2 \rightarrow 4$
- C$4 \rightarrow 2 \rightarrow 3 \rightarrow 1$
- D$4 \rightarrow 3 \rightarrow 1 \rightarrow 2$
