The correct sequence of steps in Bio-gas production is ________.

Step-by-step solution

Biogas production involves the anaerobic digestion of complex organic matter, which occurs in three main stages: 1. Hydrolysis: Complex organic polymers like carbohydrates, proteins, and lipids are broken down into simpler soluble monomers such as sugars, amino acids, and fatty acids by hydrolytic bacteria. 2. Acidogenesis: The simple monomers are converted into volatile fatty acids, acetic acid, hydrogen, and carbon dioxide by acidogenic bacteria. 3. Methanogenesis: Methanogenic archaea convert the acetic acid, hy
