<P> The total live biomass on Earth is about 550 - 560 billion tonnes C , and the total annual primary production of biomass is just over 100 billion tonnes C / yr . The total live biomass of bacteria may be as much as that of plants and animals or may be much less . The total number of DNA base pairs on Earth , as a possible approximation of global biodiversity , is estimated at ( 5.3 ± 3.6 ) x 10 , and weighs 50 billion tonnes . In comparison , the total mass of the biosphere has been estimated to be as much as 4 x 10 tonnes of carbon . </P>
