Explanation:

Biomass is a biological material, that is obtained from living or recently living plant matter such as trees, crops that can be processed into fuel and heat. Biomass is a carbon neutral fuel, it takes carbon out of the atmosphere while it is growing and returns the same amount back as it is burnt. It is managed on sustainable basis.

Cow manure produces around 12% of biomass, since it is used for heating purposes, and wood is the most common type of biomass fuel. Whilst corn is used unanimously by farmers to produce biomass to make ethanol.
