The carbon isotope cycle refers to the movement and exchange of carbon isotopes, particularly $$^{12}C$$ and $$^{13}C$$, through various Earth systems including the atmosphere, oceans, and living organisms. This cycle plays a crucial role in understanding how carbon is cycled in nature, influencing climate and biological processes. Variations in the abundance of these isotopes provide insights into carbon sources and sinks, as well as historical climate changes.
