Detailed Solution

Biogas is a mixture of methane, Carbon dioxide, hydrogen, and hydrogen sulfide. The following steps are involved in obtaining biogas Mixing the Slurry of cattle dung and watery Digesting decomposition of cattle dung by anaerobic bacteria and thus it is the formation of biogas.
Biogas is a mixture of methane carbon dioxide and hydrogen sulphide. There are four major steps involved in biogas production:

● Hydrolysis: Large organic molecules such as proteins, carbohydrates, and lipids are allowed to break down into simpler units with the help of certain enzymes.

● Fermentation: Here in this step the fermentation of organic products takes place and yields many products like organic acids, alcohols, amino acids, and CO2 which can be used in the next level

● Methane formation: Methane gas is produced

● The residue will be left after the formation of biogas(spent slurry)
