問 9
4 点The concept of dynamic equilibrium is central to understanding natural systems.
(a) Describe what is meant by 'dynamic equilibrium' within the water cycle.

5 点Analyze the relationship between positive and negative feedback loops in the regulation of the carbon cycle.
(a) Explain how a negative feedback mechanism can act as a regulator to maintain the balance of carbon in the atmosphere.
(b) Contrast this with a positive feedback loop, describing how it can lead to further instability in the global climate system when temperatures rise.
