Question

when biogeochemical cycles are impacted by humans, they tend to destabilize themselves. this destabilization causes further destabilization of the cycle resulting in further destabilization. this is an example of which type of feedback loop? negative feedback loop positive feedback loop

Explanation:

In a positive feedback loop, a change leads to more of the same change. Here, human - caused destabilization of biogeochemical cycles causes further destabilization, which is characteristic of a positive feedback loop. In a negative feedback loop, a change would lead to a response that counteracts the change.

Answer:

B. positive feedback loop
