Plants take in atmospheric carbon dioxide by photosynthesis, and are ingested by animals.So, every living thing is constantly exchanging carbon-14 with its environment as long as it lives. The carbon in its body will remain until it decomposes or fossilizes.It may be that these exceptionally harsh growing conditions are the key to understanding why some of these Bristlecone Pines have so many rings that they appear to live about ten times longer than BCPs which are growing in comparatively good conditions!Perhaps the best evidence that some BCPs can grow multiple rings per year is the fact that it has already been demonstrated.The older parts of the chronology come from dead wood found lying on the ground near the living trees.
Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.
