Name the steps of biogas production

Explanation

**Step-by-Step Solution for Biogas Production:**

1. **Decomposition**: The first step in biogas production involves the breakdown of biomass, which includes organic materials such as proteins, fats, and cellulose. This process is facilitated by various microbes that secrete enzymes like lipase, protease, and hemicellulase to degrade these complex compounds into smaller monomers.

2. **Fermentation**: After decomposition, the resulting monomers undergo fermentation. This process occurs under anaerobic (absence of oxygen) conditions, where the organic materials are converted into organic acids. This step is crucial as it prepares the substrates for the next stage of biogas production.

3. **Methanogenesis**: The final step involves the conversion of organic acids into methane. This process is carried out by methanogenic bacteria, which thrive in anaerobic conditions. The methane produced is the primary component of biogas, along with carbon dioxide and trace amounts of other gases.
