Read the poem written below and then answer the questions from the information gathered from the book or elsewhere.
Name the two kinds of waste that need to be separated from each other in two different waste bins.
उत्तर
Biodegradable waste and non-biodegradable waste are the two types of waste. With the help of microbes, biodegradable waste is easily converted into simpler forms and used as manure. Non-biodegradable trash, on the other hand, cannot be transformed into simpler forms but can be recycled. Hence, they must be kept separate.
