biomass

Since protein constitutes the majority of the biomass of a cell, building new protein is a major way that cells increase their size.

In the untouched Shangri-la-like Kingman Reef in the Line Islands in the central Pacific, sharks make up 75 per cent of the fish biomass.

Advanced technologies such as gasifier/gas turbine systems for electric power generation and fuel cells for transportation make it possible for biomass to provide a substantial share of world energy in the decades ahead, at competitive costs.
