After plants <a href="https://interviewquestions.tuteehub.com/tag/die-951171" style="font-weight:bold;" target="_blank" title="Click to know more about DIE">DIE</a> or they are consumed by other organisms (for example, by humans or other <a href="https://interviewquestions.tuteehub.com/tag/animals-875924" style="font-weight:bold;" target="_blank" title="Click to know more about ANIMALS">ANIMALS</a>), the incorporation of all carbon isotopes, including 14C, stops. Thereafter, the concentration (fraction) of 14C declines at a fixed exponential rate due to the <a href="https://interviewquestions.tuteehub.com/tag/radioactive-2970069" style="font-weight:bold;" target="_blank" title="Click to know more about RADIOACTIVE">RADIOACTIVE</a> decay of 14C.</p></body></html>
