Which of the following is a biodegradable waste A) Radioactive waste B) Aluminium cans C) DDT D) Cattle dung
Hint: Biodegradable waste means any organic matter in waste which can be broken down into simple organic compounds like carbon dioxide, water, methane by microorganisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes.
Complete answer: In this question we have asked which of the following is a biodegradable waste so first of all what is biodegradable waste as we already mentioned biodegradable waste includes any organic matter in waste which can be broken down into simple organic molecules by microorganisms. Whereas the substance that cannot be decomposed by the natural decomposers is called as non - biodegradable such as plastics. So, our first option is radioactive waste: radioactive waste typically comprises a number of unstable configurations of element the decay emitting ionizing radiation. In fact, radioactive waste is the most harmful waste because it is non - biodegradable so option A) that is radioactive waste is not correct. Option B is aluminium can: Aluminium can is not biodegradable as it is a metal and microorganism cannot be composed of metal but it does break down by oxidation over a long period of time. So, option B is also wrong. Our next option is DDT, which is the common name of dichlorodiphenyltrichloroethane; it is an organochlorine crystal that is non - biodegradable. Presence of DDT in plastic bag polythene glass objects etc. makes them non - biodegradable. So, this option is also wrong. Option D is cattle dung: The cow dung causes a wide range of protein hemicellulose and cellulose; it is also lightweight and low cost which makes it biodegradable. So, cow dung is biodegradable and the correct option is D cow dung.
>The correct option is d) cow dung
Note: As we already mentioned, only organic compounds are biodegradable. So, in the given options only one option is organic compound. So, we can solve this question by hint only.
