While the way in which nitrogen moves throughout different reservoirs on Earth makes up a cycle, it is not a process that exists within a bubble. The different components of the nitrogen cycle interact either directly or indirectly with other cycles, such as the oxygen and carbon cycles. What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles? Are any of these interactions between the cycles positive? Are any negative? What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it? How can that influence the oxygen and carbon cycles? Are there other cycles involved that have not been mentioned in this question? Finally, what does this discussion suggest about the nature of the Earth as one large system?
