(This, in turn, is caused by variations in the magnetic fields of the earth and sun, for example.) Although the ratio of radiocarbon to stable carbon in the atmosphere has varied over time, it is quite uniform around the globe at any given time because the atmosphere mixes very quickly and constantly.Plants obtain all their carbon atoms from the atmosphere.

It traps the heat of the sun within the atmosphere and hence prevents the Earth from freezing.- The primary producers (green plants), also known as photoautotrophs, are constantly removing carbon dioxide from the atmosphere through the process of photosynthesis (the process in which green plants make food for themselves in presence of sunlight).Certain bacteria, also referred to as chemoautotrophs, use carbon dioxide to synthesize the organic compounds they need.There is a constant exchange of carbon between the biotic and the abiotic world, thus forming a cycle which is called the carbon cycle.This cycle plays an important role in maintaining proper levels of carbon in the Earth's atmosphere. BASIS OF RADIOCARBON DATING Radiocarbon dating compares the amount of normal carbon with the amount of radioactive carbon in a sample.
