Carbon Sink - GCSE Biology Definition
Reviewed by: Lára Marie McIvor

A carbon sink is a natural system that absorbs more carbon dioxide from the atmosphere than it releases, helping to reduce the amount of greenhouse gases and combat climate change. Plants, oceans, and soil are the main examples of carbon sinks. Trees and other plants use carbon dioxide during photosynthesis to make food, storing the carbon in their leaves, stems, and roots. Oceans absorb carbon dioxide directly from the air and store it in the water. By capturing and holding carbon, these sinks play a crucial role in maintaining the balance of gases in our atmosphere, which is important for keeping Earth's climate stable.
