The residue left after methane production from cattle dung is:

a. burnt
b. buried in landfills
c. used as manure
d. used in civil construction

Answers (1)

The answer is option (c) used as manure.

Explanation: After methane is extracted from cattle dung, the leftover material remains nutrient-rich and can be used as a fertilizer, making it an excellent manure for plants. Some points to keep in mind:

  • Manure usage: The residue is commonly applied to soil to enhance its fertility.
  • Not for burning or landfills: It is not ideal to burn or bury the residue, as these methods are less efficient.
  • Not suitable for construction: The residue lacks the necessary properties for use in civil construction.
