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

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, hydrogen, and carbon dioxide into methane and carbon dioxide (biogas).

The correct sequence is Hydrolysis \rightarrow Acidogenesis \rightarrow Methanogenesis.

Answer: Hydrolysis \rightarrow Acidogenesis \rightarrow Methanogenesis
