Define “carbon source” and “carbon sink.” Give two examples of each.
A carbon source is a process or organism that releases carbon into the atmosphere, such as the burning of fossil fuels or the respiration of plants. A carbon sink is a process or organism that absorbs carbon from the atmosphere, such as the photosynthesis of plants or the ocean's ability to absorb carbon dioxide.
Examples of carbon sources include burning fossil fuels for energy and deforestation. Examples of carbon sinks include forests and oceans.
