प्रश्न
Explain why, some materials are biodegradable but some are non-biodegradable.
उत्तर
Some materials are biodegradable, whereas some are non-biodegradable, because decomposers break down natural materials such as paper but do not break down man-made materials such as plastics. Non-biodegradable materials consist of compounds that are not degraded by decomposers, and they persist in the environment.
