Explanation:

In an experiment, the independent variable is what the experimenter changes, and the dependent variable is what is affected by the change. Here, Jack changes the amount of water given to the plants to see its effect on the number of seeds produced. The time for growing is kept constant, and using only sun - flower plants is a condition of the experiment, not a variable being tested for cause - effect relationship.

Answer:
