In order to find out the rate of decomposition of three type of solid waste, P,Q and R, scientists dumped these wastes in a restriced open low lying area. The given graph shows the rate of decomposition of these wastes.
Which of the following correctly identifies P,Q and R?

A

P-Wooden chair, Q-Cooked pulses, R-Syringe

B

P-Plastic tumbler , Q-Iron nail, R-Wrist watch

C

P-Metal sheets , Q-Jute bag, R-Banana peels

D

P-Animal exereta, Q-Aluminium foil, R-Wooden box

Text Solution

Verified by Experts

The correct Answer is:
C
According to the given graph, P is a non-biodegradable material as its amount does not reduce at all with time. is a biodegradable material and it takes more time to get decomposed as compared to R R is also a biodegradable material as it decomposes rapidly with time. Hence, P, Q. and R could be metal sheets, jute bag and banana peels. respectively.
