Get PriceBiomass energy can also be a nonrenewable energy source Biomass contains energy first derived from the sun Plants absorb the suns energy through photosynthesis and convert carbon dioxide and water into nutrients carbohydrates The energy from these organisms can be transformed into usable energy through direct and indirect means.
Get PriceAnswer 1 of 4 The first thing to do when you make a calculation of biomass is to state the time period for which it is calculated The reason for this is because biomass is biological matter and so there can be significant changes in it over a period of time These changes mean that biomass is usually expressed as a net change so the calculation would be Biomass net increase biomass.
