Though very neat diagram (and the figures are correct), it is confusing - the title says 'Biomass of Life' but it highlights the animal biomass at the top, which is a tiny fraction of overall.

One has to see the bottom portion to realize the bigger contributing components of 'Biomass of Life'.. Plants, Bacterias etc.
