Final answer:
When humans impact biogeochemical cycles, it can lead to a positive feedback loop of destabilization.
Step-by-step explanation:
When biogeochemical cycles are impacted by humans, it can lead to destabilization, which in turn can cause further destabilization of the cycle. This is an example of a positive feedback loop. In a positive feedback loop, the initial change amplifies itself, leading to a continuous cycle of destabilization.
