Paheli dug two pits, A and B, in her garden. In pit A, she put a polythene bag packed with some agriculture waste. In pit B, she dumped the same kind of a waste but without packing it in a polythene bag. She then covered both the pits with soil. What did she observe after a month?
A. Waste in pit A degraded faster than pit B.

B. Waste in pit B degraded faster than pit A.

C. Waste in both pits degraded almost equally.

D. Waste in both pits did not degrade at all.

Answer :

Waste in pit B as waste is left open i.e. without being wrapped in a polythene bag so microbes could easily degrade them as wastes come in direct contact with oxygen gas. But in pit A as wastes are wrapped in polythene bag oxygen could not enter hence the process of degradation will be slow.
