(12,761 posts)how biomass becomes atmospheric carbon. So what if there were on 25 million bison the grass they didn't eat decayed and became CO2 and methane. Now as to the corelation between modern farming and climate change there is a huge fossil fuel carbon foot print from fuel to run equipment, nitrogen fertilizers which are made from natural gas, shipping, processing and distribution of food stuff.
If it is possible that there is a greater biomass (all living organisms) on earth, which was pretty much a closed system until the industrial revolution, it has to come from the artificial increase of carbon into the biosphere.
Your chart only shows vertebrates which are a piddling amount of the total biomass on earth. Insect far out weigh vertebrates and microbes as well. So I have to discount that chart as being too limited.
