The correct Answer is:
To solve the question regarding the residue left after methane production from cattle dung, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Biogas Production**: - Biogas, primarily composed of methane, is produced through the anaerobic digestion of organic materials, including cattle dung. This process is facilitated by specific bacteria known as methanogens. 2. **Identifying the Byproduct**: - After the anaerobic digestion process, a slurry or residue is left behind. This residue is the leftover material after methane has been extracted. 3. **Analyzing the Composition of the Residue**: - The residue from the biogas production process is rich in nutrients, containing organic material, minerals, and cellulose. This nutrient density makes it valuable for agricultural purposes. 4. **Evaluating the Options**: - (a) **Burnt**: This option is incorrect because the residue is nutrient-rich and should not be wasted by burning. - (b) **Buried in landfills**: This option is also incorrect as the residue does not contain harmful substances and is beneficial for soil. - (c) **Used as manure**: This option is correct since the nutrient-rich slurry can be utilized to enhance soil quality as a fertilizer. - (d) **Used in civil construction**: This option is incorrect as the residue is not typically used in construction. 5. **Conclusion**: - The correct answer is (c) used as manure, as it effectively utilizes the nutrient-rich residue from methane production. ### Final Answer: (c) used as manure
