So, why did the constant ratio assumption turn out to be incorrect?
Actually, many reasons were found to refute the validity of this assumption.
This goes on until a very minuscule, undetectable amount remains.
In bodies less than 50,000 years in age the amount of radiocarbon can be detected.

By Kamil Erkan Libbys discovery, now known as the carbon-14 (or radiocarbon) technique, was a method that could be used to determine the age of organic remains.

This same ratio is valid in all the reservoirs of carbon in this giant cycle.
In the biosphere, both carbon-14 and carbon-12 atoms are added to the food chain via assimilation; first by plants through photosynthesis and then by animals through consumption of the plants.
Each carbon-12 atom takes up two neutrons and is converted into a radioactive carbon-14 atom.
Radioactive carbon-14 atoms rapidly mix and become uniform throughout the atmosphere.
