Q4.21. Which of the following statements about the global phosphorus cycle is true? (Hint: Please click here to see a figure of the post-industrial global phosphorus cycle.) Phosphorus applied to crops as fertilizer always stays within the terrestrial subsystem. Very little of Earth's phosphorus is found in sediments and rocks. Fertilizer application has decreased phosphorus availability in terrestrial ecosystems. The mining of phosphate ore is a significant source of phosphorus for fertilizers. Submit
