Which of the following statements about biogeochemical cycling is correct? A)The phosphorus cycle includes the recycling of atmospheric phosphorus gas. B)The phosphorus cycle involves the weathering of rocks of marine origin. C)The carbon cycle incorporates carbon dioxide produced from photosynthesis. D)The carbon cycle always maintains a constant level of atmospheric CO₂_.

Question

Quizplus · Accepted Answer

The phosphorous cycle involves the weathering of rocks of marine origin, as marine sedimentary rocks contain phosphorous that can be weathered and released into the soil and water. The other statements are incorrect: atmospheric phosphorus gas is not a significant component of the phosphorous cycle, photosynthesis produces oxygen and glucose rather than carbon dioxide, and the carbon cycle does not maintain a constant level of atmospheric carbon dioxide.
