A student conducted an experiment on the amount of food beetles consumed when placed in
three different sizes of environments. The student put 100 beetles in each of the three different
aquarium environments. The student recorded the amount of food that was eaten daily for
three weeks. What are the dependent and independent variables for this experiment?
Dependent Variable: Size of environment
Independent Variable: Amount of food eaten
Dependent Variable Size of environment
Independent Variable Number of beetles
Dependent Variable Amount of food eaten
Independent Variable Size of environment
Dependent Variable Number of beetles
Independent Variable Amount of food eaten
