500

The process in plants that allows them to absorb carbon letting it propagate through the environment.

What is photosynthesis?

500

The lithosphere plays a crucial role in the carbon cycle by storing carbon in these long-term reservoirs, formed from compacted organic matter and carbonate minerals.
