a)
Andrea is investigating the effects of light intensity and carbon dioxide concentration on the rate of photosynthesis. She measured the rate of photosynthesis at different light intensities for two identical plants. The plants were placed in closed containers. One container had an initial carbon dioxide concentration of 0.40%. The other container had an initial carbon dioxide concentration of 0.03%.
Look at the graph.
