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 (s) (noun), biomasses (pl)
Organic substances from living organisms that were recently alive, particularly of vegetation, and used as a fuel: Biomass is also especially cultivated for the purpose of fuel or as a source of energy.

Biomass is can be used to produce biofuel that is made from this organic material.

biomass fuel (s) (noun), biomass fuels (pl)
Any solid, gaseous, or liquid fuel obtained from biomass: Biomass fuel may be in its natural form (wood or peat) or from a commercially produced form (ethanol from sugarcane residue or diesel fuel from waste vegetable oils).

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 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.

biomass resource assessment (s) (noun), biomass resource assessments (pl)
An estimate of the quantities of such resources that are available by location and price levels: Biomass resource assessments must consider different factors, like practical obtainability and technical practicability, among others, to determine the usefulness of using biomass as an energy.

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.
