WebOct 10, 2024 · I understand that all living beings have the same proportion of carbon 12 to carbon 14 and that this is an assumption used to carry out carbon dating but I do not understand how this is possible. As isotopes are not evenly distributed, how can it be that the proportion of carbon 14 is the same in all living beings? WebThis carbon-14 then reacts with oxygen to form CO2, and that is absorbed by plants and algae in photosynthesis. This is how it is mixed into the other natural carbon. Since living things continuously replace their atoms while they live, but stop when they die, the ratio of carbon-14 will be the same as the natural ratio as long as they live ...
