The terrestrial carbon cycle refers to the exchange of carbon between the atmosphere, land, and oceans. This cycle is driven by processes such as photosynthesis, respiration, decomposition, and human activities such as deforestation and land use changes. Understanding the terrestrial carbon cycle is important for predicting and mitigating the impact of climate change, as carbon stored in vegetation and soils plays a crucial role in regulating the Earth's climate. Researchers study these processes using a variety of methods, including satellite observations, field measurements, and modeling techniques. By improving our understanding of the terrestrial carbon cycle, scientists can better inform policies and management strategies for carbon sequestration and climate change mitigation.
