Question

Biogas formed ________decomposition of organic waste matter.

Answer 1

$\huge \mathbb\fcolorbox{black}{plum}{Answer}$

Biogas is a form of energy produced from anaerobic decomposition of waste material and organic matter. It is a renewable source of energy and a good alternative in place of fossil fuels which are depleting with time. Biogas is produced by methanogenic bacteria which breakdown organic matter in the absence of oxygen. They produce biogas which is a mixture of gases like methane (CH4), carbon dioxide (CO2) and hydrogen (H2) in different composition.
