Question

1. sep construct an explanation develop explanations supported by models consistent with scientific ideas, principles, and theories. explain the significance of the carbon cycle to ecosystem stability.
2. analyze explain the consequences of disrupting the carbon cycle. give two examples of how humans have disrupted the carbon cycle and the consequences of that disruption.

Explanation:

The carbon cycle is crucial for ecosystem stability as it recycles carbon. Disruptions like deforestation and fossil - fuel burning increase CO₂, causing climate change.

Answer:

1. The carbon cycle is vital for ecosystem stability as it recycles carbon among atmosphere, biosphere, etc. It provides carbon for photosynthesis and respiration, maintaining balance.
2. Humans disrupt the carbon cycle by deforestation (less CO₂ absorption) and fossil - fuel burning (more CO₂ emission), leading to climate change and ocean acidification.
