Sam wished to investigate how fertilizer run-off affects the growth of algae in freshwater lakes and streams. He set his experiment up as follows. 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 lamp which was on a timer to provide 12 hours of light each day. Liquid fertilizer was added to the beakers in the following amounts.

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.

What is the independent variable in this experiment?
