How does the carbon cycle prove the
law of conservation of mass?

The movement of carbon through the carbon cycle provides a good example of how mass is conserved in living systems. The source of the carbon found in living matter is carbon dioxide that is in the air or dissolved in water.

The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.

equal distribution i think.
