Carbon is found in different forms in the environment — mainly in the stable form of carbon and the unstable form of carbon Over time, carbon decays radioactively and turns into nitrogen. A living organism takes in both carbon and carbon from the environment in the same relative proportion that they existed naturally.

Once the organism dies, it stops replenishing its carbon supply, and the total carbon content in the organism slowly disappears. Scientists can determine how long ago an organism died by measuring how much carbon dating used half life is left relative to the carbon Public Domain Image, source: Christopher S. Carbon has a half life of years, meaning that years after an organism dies, half of its carbon atoms have decayed to nitrogen atoms.

Similarly, years after an organism dies, only one quarter of its original carbon atoms are still around.
