Answer:

Carbon sources include emissions from burning fossil fuels, forest fires, and respiration. Carbon sinks include the oceans, the plants, and soil.

Explanation:

A carbon sink is growing in size and storing more carbon compared to a carbon source which is shrinking in size and releasing more carbon.

Carbon sources include emissions from burning fossil fuels, forest fires, and respiration. Carbon sinks include the oceans, plants, and soil.

Typically, sources and sinks balance one another. For example, the carbon emitted during respiration is offset by photosynthesis (see the image above). However, the burning of fossil fuels is an important carbon source.
