Answer: Independent variable is amount of sunlight
Dependent variable is height of plants
Step-by-step explanation:
An experiment is performed in which the hypothesis says that plants grow taller when they receive more sunlight. The growth of plants depends on the amount of sunlight received.
In this case the independent variable is amount of sunlight that can change in intensity. This factor can be controlled during the experiment.
The dependent variable is growth of plant or tallness of plants which can change as the intensity of light will change.
