Explanation:

An independent variable is what is changed in an experiment. Here, the amount of fertilizer given to each plant is varied while other factors like light, soil, humidity, and temperature are kept constant. The type of soil is fixed, and the height of the plant is the dependent variable (what is measured as a result of the change).
