Biomass is a term used in several contexts: in the context of ecology it means living organisms,[1] and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants,[2] from plants and algae,[3] from plants and animals.[4] The vast majority of biomass used for bioenergy does come from plants and fecal matter. Bioenergy is a type of renewable energy that the bioenergy industry claims has the potential to assist with climate change mitigation.[5]
biomass: Material produced by the growth of microorganisms, plants or animals.
