Published by Houghton Mifflin. If isotopic carbons dating show that the hydrocarbon contains 14 C at atmospheric levels, it's from a plant. GED Science - Ecology: Carbon is most abundant in atmospheric carbon dioxide because it is constantly being produced by collisions between nitrogen atoms and cosmic rays at the upper limits of the atmosphere.
