Answer 2

Answer:

(b) Mterial of B decomposes faster than A

Explanation:

since polythene bag is a non-degradable substance in nature, it doesnt allow decomposition proccess of the waste of plants with the soil, threfore, the microbes dont wrok upon it. When in the case of B, as it is put directly into the soil, the microbes responsible for the decomposition , are able to carry out this process and hence, the plant waste gets decomposed faster there.
