The biomass used for electricity generation varies by region. Forest by-products, such as wood residues, are common in the United States. Agricultural waste is common in Mauritius (sugar cane residue) and Southeast Asia (rice husks). Animal husbandry residues, such as poultry litter, are common in the UK.ugars present in this biomass are fermented to produce bioethanol, an alcohol fuel which can be used directly in a fuel cell to produce electricity or serve as an additive to gasoline. However, utilizing food-based resources for fuel production only aggravates the food shortage problem.
Food chains, pyramids of numbers and pyramids of biomass are all ways of showing how energy is passed on from one organism to another. Biomass is the food available for the next trophic level (feeding level) in a food chain. Biomass is used as a source of renewable energy to reduce our dependence on fossil fuels.he pyramid of numbers usually shows that the number of organisms at each trophic level gets smaller towards the top. This particular case is an exception â one tree provides food for many caterpillars.
