[ sĭngk ]

A part of the physical environment, or more generally any physical system, that absorbs some form of matter or energy. For example, a forest acts as a sink for carbon dioxide because it absorbs more of the gas in photosynthesis than it releases in respiration. Coral reefs are a long-lasting sink for carbon, which they sequester in their skeletons in the form of calcium carbonate.
