Phosphorus and Nitrogen Dynamics

Phosphorus and Nitrogen Dynamics and Human Influences On These Cycles
Review the biogeochemical cycles of phosphorus and nitrogen. Based on your research, answer the following questions:

1.What are the features of the phosphorus and nitrogen biogeochemical cycles and how are these similar and different from the carbon cycle? (8 marks)

2.Explain the influences that humans can have on these cycles and explain why this is the case. (2 marks)

3.Based on your research, indicate whether the following question is true or false and defend your conclusion based on the research information available: If we don’t change our demands on nitrogen and phosphorus, we will run out of them in the near future. (10 marks)
