Carbon Sources and Carbon Sinks

Carbon sinks are living things or objects that take in carbon. The difference between carbon sinks and carbon sources is that carbon sinks take in carbon and carbon source release or store carbon. A few examples of carbon sinks are redwood trees, landfills, and the ocean.
Carbon sources are living things or objects that contain and give off carbon. Carbon sources can be identified by the actions of the living things or the objects. For example, a carbon source is people breathing, driving a car, factory gases, or burning fossil fuels. When carbon is released, scientists call the objects or living things release agents.
