Explanation

Rottening - means decaying of the material. It is a natural breakdown of complex organic compounds into simpler substances. Rottening or decay occurs in dead plants & animal tissues. i.e. Rottening occurs in biodegradable waste. All the waste derived from living matter is biodegradable. Leather - is animal skin that has been chemically modified to produce strong flexible materials. Therefore, it is a biodegradable waste. Coconut - is a hard shelled fruit containing juice. Therefore, coconut is also biodegradable waste material hence both leather & coconut can be rotten down.
