Radiocarbon is then taken in by plants through photosynthesis, and these plants in turn are consumed by all the organisms on the planet.

Although relative dating can work well in certain areas, several problems arise.

Rodents, for example, can create havoc in a site by moving items from one context to another.

Since plankton is the foundation of the marine food chain, Carbon-14 is spread throughout aquatic life.

Shellfish remains are common in coastal and estuarine archaeological sites, but dating these samples require a correction for the “reservoir effect” a process whereby "old carbon" is recycled and incorporated into marine life especially shellfish inflating their actual age in some cases several centuries.

Natural disasters like floods can sweep away top layers of sites to other locations.

Absolute dating represents the absolute age of the sample before the present.For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).The Greeks consider the first Olympic Games as the beginning or 776 BC.Relative dating stems from the idea that something is younger or older relative to something else.In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.Plants are not the only organism that can process Carbon-14 from the air.
