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:

A positive feedback loop amplifies changes, leading to more of the same effect. Here, human impact on biogeochemical cycles causes destabilization, which then leads to further destabilization (amplifying the initial change), matching the positive feedback loop definition. A negative feedback loop would work to stabilize or reverse a change, which is not the case here.

Answer:

positive feedback loop
