Answer 1

The biosphere plays a crucial role in the carbon cycle, as it facilitates the exchange of carbon among living organisms through processes like photosynthesis and respiration. Without the biosphere, the carbon cycle would be severely disrupted; carbon would primarily remain in the atmosphere, oceans, and geological formations, limiting its availability for organic processes. While some aspects of the carbon cycle, such as geological processes and oceanic carbon absorption, could still occur without life, the dynamic balance and recycling of carbon as organic matter would be absent, leading to a stagnant carbon system. Thus, the biosphere is essential for a functioning and balanced carbon cycle.
