Which is a sink for carbon dioxide?

Question

Quizplus · Accepted Answer

Photosynthesis is the process by which green plants absorb carbon dioxide during the day and convert it into organic matter. This process is a sink for carbon dioxide, as it removes carbon dioxide from the atmosphere and stores it in organic compounds. The other options (B, C, and D) are not carbon dioxide sinks. Ultraviolet radiation does not remove carbon dioxide from the atmosphere, soil bacteria release carbon dioxide into the atmosphere, and volcanoes emit carbon dioxide into the atmosphere.
