Answer:
Independent variable: Amount of sunlight
Dependent variable: Plant height
Explanation:
The independent variable is the one that a scientist intenionally changes in an experiment, while the dependent variable is the one that changes in response to the independent variable. In this case, the amount of sunlight given to each plant is intentionally varied so it is the independent variable, while the height of each plant depends on the amount of sunlight given so it is the dependent variable.
