carbon source
Plants take in carbon from carbon dioxide in the air and convert it to carbohydrates and keep it with them.
carbon sink
Other than photosynthesis, the formation of carbonates in the ocean traps carbon from the atmosphere.
Yes, deforestation removes trees that act as a carbon sink, removing and storing carbon dioxide from the atmosphere. This increases the greenhouse effect.
Trees absorb carbon dioxide (when talking about a "carbon sink", it means the carbon as any form).
Other than photosynthesis, the formation of carbonates in the ocean traps carbon from the atmosphere.
Photosynthesis is the process by which chlorophyll dissociates water into its components of hydrogen and oxygen. The plant expels the oxygen as a waste gas, but the hydrogen is used to build complex biochemicals, such as plant tissue. The chemical energy from the photosynthesis is stored in sugars derived from carbon dioxide and water. Thus the plant absorbs CO2.
Decaying vegetation is actually the opposite of a carbon sink. A carbon sink is something that takes carbon out its natural cycle and stores in for an extended period of time. Vegetation, particularly trees, absorb carbon, and thus they act as stores. However, decaying vegetation releases the carbon back into the air as it decays. Therefore, it is not a sink.
Trees absorb carbon dioxide (when talking about a "carbon sink", it means the carbon as any form).
Carbon sequestration refers to the process of capture and long term storage of the atmospheric carbon dioxide. The carbon sink refers to the natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period.
carbon source
heat sink is when heat is absorbed into any type of environment, including the aquatic ecosystem; and carbon sink is when CO2 is absorbed into any type of environment including the terrestrial ecosystem.
Carbon found within limestone rocks.
The ocean. Limestone.

No, subduction does.
