The carbon cycle refers to the process through which carbon is moved between the atmosphere, oceans, plants, soil, and animals. There are several synonyms for the term "the carbon cycle" that are often used interchangeably, including the carbon dioxide cycle, the carbon exchange cycle, and the carbon recycling process. These synonyms highlight different aspects of the cycle, but all describe the same fundamental process of carbon movement and transformation. Understanding the carbon cycle is critical to understanding climate change and global warming, as the build-up of carbon dioxide and other greenhouse gases in the atmosphere disrupts this delicate balance and leads to overheating of the planet.
