Researchers determined that Dawsonia moss acts as a physical buffer that reduces water's ability to erode the soil and carry away its nitrogen. They are now interested in determining whether the moss must be alive to prevent nitrogen loss, or do dead moss have the same effect? Arrange the following steps in the correct sequence to test this hypothesis. 1. Add herbicide to the soil of the experimental plot of mosses. 2. Apply water equally to the experimental and control plots. 3. Measure initial soil nitrogen contents of control and experimental plots. 4. Quantify nitrogen loss from the soil of control and experimental plots. 5. Establish two identical plots of moss; one as a control, the other as the experimental treatment.
