Question

when the biogeochemical cycles are functioning normally, they stabilize themselves after a disturbance and return to a normal state. this internal stabilization of the cycle is an example of what? positive feedback loop negative feedback loop

Explanation:

• A negative feedback loop counteracts changes. When the biogeochemical cycle is disturbed, it works to reduce the disturbance and return to normal.
• A positive feedback loop amplifies changes, which is not the case here as the cycle is trying to stabilize (reduce the effect of the disturbance).

Answer:

Negative feedback loop
