From that point onwards, the unstable carbon-14 decays with its half life of almost 5700 years, and the amount of carbon-12 remains the same.
Hence, gradually, the ratio of stable carbon to radioactive carbon also decreases.

As creatures consume carbon from their environment and incorporate it into their bodies, they consume both carbon-12 and carbon-14.
When a creature dies, it ceases to consume more carbon.
Plants get their share of carbon atoms from the atmosphere. It is seen that at any given point of time, the ratio of stable carbon and radiocarbon in the atmosphere, is almost same as the ratio of stable carbon and radiocarbon in living organisms like plants, animals, and humans.
When a living organism dies, its carbon intake ceases.
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.
For example, logs of woods cut from different trees were burnt in a fireplace.
The sample of the end result would be contaminated.
ANSWER: To understand how carbon 14 dating works, you first have to understand what carbon-14 is and what part it plays in our biosphere. As they live and grow and interact with their environments they consume more and more carbon.
By far, the most abundant form of carbon is carbon-12.
If either assumption is wrong carbon-14 dating doesn't work.Tags: Adult Dating, affair dating, sex dating
