Luisa is studying how light affects photosynthesis in an aquatic plant. She places a piece of the plant in a test tube and holds it near a light. Then she measures the number of oxygen bubbles produced by the plant. She moves the light farther away from the plant and repeats the experiment. The graph shows Luisa’s results. © 2017 Measured Progress. All rights reserved.

Describe the inputs and outputs in the model. b. Explain how increasing the amount of light will affect one output of this model. Support your explanation with data from the graph.
