A student placed a test tube containing elodea (an aquatic plant) and pond water 10 cm from a light source. He observed that the plant
gave off bubbles of a gas and counted how many bubbles were
released in one minute. He moved the plant farther away from the
light source to see if distance from the source made a difference. The
data table below shows his results.
