what types of organisms have the highest productivity
Biomass (ecology) The total live biomass on Earth is about 550 - 560 billion tonnes C,[1][5] and the total annual primary production of biomass is just over 100 billion tonnes C/yr.[6] The total live biomass of bacteria may be as much as that of plants and animals[7] or may be much less.[8] The total number of DNA base pairs on Earth, as a possible approximation of global biodiversity, is estimated at (5.3Â±3.6) x 1037, and weighs 50 billion tonnes.[9][10] In comparison, the total mass of the biosphere has been estimated to be as much as 4 x 1012 tonnes of carbon.[11]
