biomass (s) (noun), biomasses (pl)
1. The total amount of living material within a given unit of an environmental area: "The total living biomass of bacteria may exceed that of plants and animals."
2. Plant material, vegetation, or agricultural waste that is used as a fuel or as a source of energy: "Efforts are being made to utilize more vegetable matter to produce fuel for all aspects of energy uses."

"Any solid, gaseous, or liquid fuel obtained from biomass may come from natural forms: such as, wood, peat, or a commercially produced form including ethanol from sugarcane residue; and diesel fuel can also be produced from waste vegetable oils."

"Biomass is a collective term for all organic substances of relatively recent (non-geological) origin that can be used for energy production, including industrial, commercial, and agricultural wood and plant residues; municipal organic waste; animal manure; and crops directly produced for energy purposes."

biomass (adjective), more biomass, most biomass
1. A reference to vegetable materials that are used as a source of green energy-fuel production: "The biomass stations in some places are generating electricity."
2. Pertaining to living organisms, plant and animal, in a particular geographical area: "The biomass species for each section include micro-organisms, plants, and animals."

"It has been estimated that there are about five million trillion trillion, or 5 × 1030 (5 nonillion) biomass bacteria on Earth with a total biomass equaling that of plants. Some researchers believe that bacteria are, and always have been, the dominant biomass forms of life on Earth exceeding the total of all plants and animals."

biomass [integrated] gasification
A composite system used to convert materials of feedstock into gas fuel for an electricity-generating unit that consists of one or more gas turbines, with a portion of the required energy input provided by the exhaust heat of the turbine to increase efficiency.

biofuel, biomass fuel
1. A solid, liquid, or gaseous fuel that is obtained from biological raw material; the conversion is accomplished through thermochemical or biological methods.
2. Gas such as methane or liquid fuel such as ethanol (ethyl alcohol) made from organic waste material, usually by microbial action.
3. A renewable fuel, e.g., biodiesel, biogas, and methane, that is derived from biological matter.
biomass combustion
A technology that extracts heat energy from natural materials so it can then be used for a variety of heat and power applications.
biomass energy
A general term for renewable energy produced from plants, etc ; such as, wood and wood wastes, agricultural crops and wastes, or municipal and industrial wastes: "Biomass energy is the chemical energy content of non-fossil, energy-containing forms of carbon; such as, land-based and water-based vegetation, and waste materials; such as, municipal solid wastes, biosolids, forestry, and agricultural residues, and some industrial wastes."

biomass oil
An energy produced from materials in the form of lipids from animal fats, fish, and poultry oils, plant oils, or recycled cooking greases.
biomass resource
Any form of organic material that can be used as an energy source; such as, forest, mill, and agricultural residues, urban wood wastes, and dedicated energy crops: "A biomass resource assessment estimates the quantities of such resources available by locations and price levels."
biomass supply curve
An estimate of the quantity of natural resources that can be made available as a function of their price.
marine biomass (s) (noun) (no pl)
A collective term for all organic substances of marine origin: Marine biomass can be exemplified by large seaweeds which are utilised in producing the manufactured kelp.
virgin biomass
Living vegetation that has the potential for use as energy, as opposed to processed or waste materials.
waste biomass (s) (noun), waste biomasses (pl)
A collective term for substances, including municipal sewage, manure, forestry and agricultural residues and some types of unusable industrial products: The municipal engineers studied the waste biomass to determine what could be recycled into safe products.

biomass
1. The dry weight of living organic matter in a particular ecosystem.

Units are grams of organic matter per square meter.

2. Plant-derived material usable as a renewable energy source, including wood energy crops; such as, hybrid poplars and willow trees, agricultural crops including soybeans and corn, and animal and other wastes.

Biomass is one of the two most common energy sources in the U.S. today, along with hydropower. Forms of biomass; such as, wood can be burned to produce heat and generate electricity.

Agricultural crops can be chemically converted into fuels; such as, ethanol and biodiesel; these are the only known renewable liquid energy sources, and may one day replace petroleum and fossil-fuel.

biomass in the ecology
The total mass of living organisms present in a given area.

It may be specified for a particular species; such as, earthworm biomass or for a general category; such as, herbivore biomass.

Estimates also exist for the entire global plant biomass and measurements of biomass can be used to study interactions between organisms, the stability of those interactions, and variations in population numbers.

Whenever dry biomass is measured, the material is dried to remove all water before weighing.

biomass waste
Organic non-fossil material of biological origin that is a byproduct or a discarded product.

Biomass waste includes municipal solid waste from biogenic sources, landfill gas, sludge waste, agricultural crop byproducts, straw, and other biomass solids, liquids, and gases; but it excludes wood and wood-derived fuels (including black liquor), biofuels feedstock, biodiesel, and fuel ethanol.

It should be noted that some so-called biomass waste also includes energy crops grown specifically for energy production, which would not normally be considered waste.

hydrothermal biomass
Described as being a biomass between 10,000 and 100,000 times greater than the general abyssal environment.

Just like an oasis in the desert, these toxic sites attract an entire peripheral fauna constituted of sessile crustaceans; such as, the vent barnacles, which resemble a flower, or mobile crustaceans, like spider crabs.

oceanic biomass
The total quantity or mass of living material within a specified area of the ocean at a given time.

The concept of biomass allows people to express the idea of the abundance of animal presence in volume without having to use headcounts as is the case when speaking of density.

It is useful in that living organisms vary too broadly in size for density to be a meaningful measure.
