Plant matter, such as wood, which can be used as source of energy.
Energy Glossary
Energy resources derived from organic matter. These include wood, agricultural waste and other living-cell material that can be burned to produce heat energy. They also include algae, sewage and other organic substances that may be used to make energy through chemical processes.

is the total dry weight of living material in a particular area.
Fishery Glossary
1. The total weight of the living organisms concerned, whether in a system, a stock, or a fraction of a stock: e.g. plankton biomass in an area, biomass of spawners or of newly recruited fish.
2. Or standing stock. Total weight of a resource, a stock, or a component of such stock. Examples: the biomass of all demersal fish on the Georges Bank; the biomass of the cod stock; the spawning biomass (i.e. the weight of mature females).

Biomass is biological material derived from living, or recently living organisms. It most often refers to plants or plant-based materials which are specifically called lignocellulosic biomass. As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: thermal, chemical, and biochemical methods.

Total dry weight of all living organisms that can be supported at each tropic level in a food chain. Also, materials that are biological in origin, including organic material (both living and dead) from above and below ground, for example, trees, crops, grasses, tree litter, roots, and animals and animal waste.

Environmental Engineering (English ver.)
(1) The total mass of living matter within a given unit of environmental area. (2) Plant material, vegetation, or agricultural waste used as a fuel or energy source. (3) The total quantity of plants and animals in a lake. Measured as organisms or dry matter per cubic meter, biomass indicates the degree of a lake system's eutrophication or productivity. Some methods of determining biomass in a sample include: (1) Ash Mass: The mass or amount of residue present after the residue from the dry mass determination has been ashed in a muffle furnace at a temperature of 500C for 1 hour. The ash mass values of zooplankton and phytoplankton are expressed in grams per cubic meter (g/m3), and periphyton and benthic organisms in grams per square mile (g/mi2). (2) Dry Mass: The mass of residue present after drying in an oven at 105C for zooplankton and periphyton, until the mass remains unchanged. This mass represents the total organic matter, ash and sediment, in the sample. Dry-mass values are expressed in the same units as ash mass. (3) Organic Mass or Volatile Mass: Refers to the mass of a living substance as the difference between the dry mass and ash mass and represents the actual mass of the living matter. The organic mass is expressed in the same units as for the ash mass and dry mass. (4) Wet Mass: The mass of living matter plus contained water.
