Jake set up an experiment. He set two aquariums with five fish of the same type and size. Aquarium one was very small, only one cubic foot. Aquarium 2 was very large at 10 cubic feet. Each day the fish were fed the same amount of food and vitamins, at the end of 5 months Jake measured the fish by length. His results are shown in the bar graph above.
