The primary carbon-containing compound in the atmosphere is carbon dioxide, and a very small amount of carbon dioxide contains C-14.

Plants absorb C-14 during photosynthesis, so C-14 is incorporated into the cellular structure of plants.

Carbon-14 dating can only be used to determine the age of something that was once alive.
