You're Conducting an Experiment to Determine the Effect of Different

Multiple Choice

You're conducting an experiment to determine the effect of different wavelengths of light on the absorption of carbon dioxide as an indicator of the rate of photosynthesis in aquatic ecosystems. If the rate of photosynthesis increases, the amount of carbon dioxide in the environment will decrease, and vice versa. Small aquatic plants are placed into three containers of water mixed with carbon dioxide. Container A is placed under normal sunlight, B under green light, and C under red light. The containers are observed for a 24-hour period.
-Based on your knowledge of the process of photosynthesis, the plant in the container placed under red light would probably

A) absorb no CO₂.
B) absorb the same amount of CO₂ as the plants under the green light.
C) absorb less CO₂ than the plants under the green light.
D) absorb more CO₂ than the plants under the green light.
