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? negative feedback loop positive feedback loop

Explanation:

A negative feedback loop works to stabilize a system by counteracting changes and returning it to a normal state. In biogeochemical cycles, after a disturbance, the cycle self - stabilizes and returns to normal, which matches the function of a negative feedback loop. A positive feedback loop amplifies changes, moving the system further from its original state, so it doesn't fit here.

Answer:

Negative feedback loop
