Earth’s carbon cycle works on a global scale. But it can be affected by the tiniest of organisms: soil microbes. These microbes decompose organic matter like plant litter and dead organisms, and create simple carbon compounds. These simple carbon compounds can then be used by other organisms, or turned into gases (like carbon dioxide) and released into the atmosphere.
