Solution
Correct Answer:
Cellulose-rich biomass
- Biogas: A mixture of gases (primarily Methane and CO2) produced by the anaerobic breakdown of organic matter.
- Methanogens: These are anaerobic bacteria (like Methanobacterium) commonly found in anaerobic sludge and the rumen of cattle.
- Feedstock: They act on waste materials rich in cellulose (e.g., cow dung or 'gobar', plant remains).
- The Process: Methanogens decompose cellulose and other organics into simpler molecules, finally producing methane as a metabolic byproduct.
This medium difficulty biology question is from the chapter biology and human welfare, covering the topic of waste management. It appeared in the 2025 exam.
