Biogeochemical Cycles Flashcard

Front

Where does the phosphorous cycle begin?

Back

Rocks

Front

Which cycle is considered the slowest? Options: Carbon, Hydrologic (Water), Phosphorous, Nitrogen

Back

Phosphorous

Answer explanation

Phosphates move quickly through plants and animals; however, the processes that move them through the soil or ocean are very slow, making the phosphorus cycle overall one of the slowest biogeochemical cycles.

Front

Which cycle is driven by the Sun? Options: Nitrogen, Hydrologic (Water), Carbon, Phosphorous

Front

Which process captures carbon dioxide from the atmosphere and uses it to make sugar?

Back

Photosynthesis
