The following question has two parts. First, answer part A Then answer part B
Part A
Students investigate how light intensity affects the rate of photosynthesis in an aquatic plant
Theu setup is shown in the diagram.
Light Intensity Investigation
0m
0.5 m
The students place a light at different distances from the plant and record the number of bubbles
produced. Their data are shown in the table.

Which inference is supported by the data?
A
The plant produces more oxygen as light intensity increases.
B
The plant takes in more water when the light intensity decreases.
C
(D
The plant requires more energy for photosynthesis at lower light intensities.
The plant needs less carbon dioxide for photosynthesis at higher light intensities.
