In most aquatic environments, primary production is affected by the light available to the community of organisms. Using measurements of dissolved oxygen concentration to determine primary productivity, design a controlled experiment to test the hypothesis that primary productivity is affected by either the intensity or the wavelength of light. In your answer, be sure to include the following. • • • A statement of the specific hypothesis that you are testing A description of your experimental design (Be sure to include a description of what data you would collect and how you would present and analyze the data using a graph.)
