The biosphere is part of the carbon cycle, but what if there were no biosphere? Is the biosphere necessary for the carbon cycle ? In 3-5 simple sentences, explain why or why not.

Answer 1

Yes, the biosphere is necessary for the carbon cycle. The biosphere, which includes all living organisms on Earth, plays a crucial role in the carbon cycle by both absorbing and releasing carbon dioxide through processes like photosynthesis and respiration. Without the biosphere, there would be no plants to absorb carbon dioxide, leading to an imbalance in atmospheric CO2 levels and disrupting the carbon cycle. Additionally, the biosphere is responsible for storing carbon in organic matter, such as trees and soil, helping to regulate the carbon cycle and mitigate climate change.
