Ty wished to investigate how fertilizer run-off affects the growth of algae in freshwater lakes and streams. Ty set his experiment up in the following way: He placed 900 ml of water into each of five 1000 ml glass beakers. To each beaker, he added 5 ml of water from an aquarium which contained a large concentration of algae. The beakers were placed under a grow light which was timed to provide 12 hours of light each day. Liquid fertilizer was added to the beakers in the following amounts: Beaker A - 8 ml fertilizer, Beaker B - 6 ml fertilizer, Beaker C - 4 ml fertilizer, Beaker D - 2 ml fertilizer, and Beaker E - no fertilizer. Each week a random sample from each of the beakers was examined under a microscope to get a count of the number of algal cells present.
