It is often used in archeology and some types of biology. Plants (and other autotrophs) take in carbon dioxide gas from the atmosphere during photosynthesis.
Animals (and other heterotrophs) get their carbon by eating plants or other animals, from decaying organic matter, or from other similar sources.
He claimed that it was capable of dating animal, plant and human remains of fairly recent origin. As they say on Star Trek, we are all carbon based units.
Laboratory research has shown that the radioactive decay of Carbon-14 occurs in a half-life of 5,73040 years through beta decay that causes the Carbon-14 to revert back to Nitrogen-14.
There is a small amount of radioactive carbon-14 in all living organisms because it enters the food chain.There are more than 80 such technologies that are claimed to work.Prior to looking at the many flaws in the Carbon-14 Dating Technique, it should be noted that no radiometric technique is reliable.Before the nuclear age, the amount of radiocarbon in the environment varied little in the span of a century.In contrast, from 1955 to 1963, atmospheric radiocarbon levels almost doubled.Most autotrophs use sunlight in the process of photosynthesis to make..Photosynthesis is the name of the process by which autotrophs (self-feeders) convert water, carbon dioxide, and solar energy into sugars and oxygen.
