Where it comes from

From bio- (prefix denoting organic life) + mass (“matter, material”).

noun biomasses

  1. uncountable, usually The total mass of a living thing or a part thereof (such as a cell). Since protein constitutes the majority of the biomass of a cell, building new protein is a major way that cells increase their size.
  2. uncountable, usually The total mass of all, or a specified category of, living things within a specific area, habitat, etc. 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.
  3. uncountable, usually Organic matter derived from living things that were recently alive (especially vegetation) used as a fuel or source of energy, especially if cultivated for that purpose; also, fuel produced from such organic matter; biofuel. 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.
