Q2. To test the hypothesis that one nutrient is limiting, the best experimental design is to: Increase the input rates of all nutrients simultaneously. Increase the input rate of a single nutrient at a time. If population growth increases with an increase in the input rate of one nutrient, no others need be tested. Increase the input rate of a single nutrient at a time, testing all nutrients under consideration. All of the above are equally good designs.
