Answer:
c. Independent = Fertilizer amount, Dependent = Yield
Explanation:
In an experiment, the independent variable is changed to observe its effect on the dependent variable. In the given experiment, the potted tomato plants were treated with different amounts of fertilizer to observe the effect of the amount of fertilizer on the plant yield. Therefore, the amount of fertilizer is an independent variable here. Since the effect of change in the amount of fertilizer was observed in terms of plant yield, the "plant yield" is a dependent variable in the experiment.
