By far, the most abundant form of carbon is carbon-12.
Carbon-12 is a stable isotope; that is, it doesn't decay naturally.
Carbon-14 on the other hand is an unstable isotope; that is, it decays naturally over time. It is produced naturally in the atmosphere and mixes with carbon-12 becoming part of our planet's biosphere.
Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.
