Explanation: degradable waste: degradable such as organic waste can be decomposed into useful manure such degradation involves the activity of micro organisms

non degradable waste: non degradable part such as plastic cannot be decomposed in the soil  

that is why some substances are biodegradable and some non-biodegradable                                                                                                                    

       

Answer 2

HEY FRIEND HERE IS UR ANSWER,

The reason why some substances are biodegradable and some non-biodegradable is because the microorganisms like bacteria and decomposers like saprophytes have a specific role to play. They can breakdown only natural products like paper, wood etc. but they cannot breakdown man-made products like plastics. Based on this some substances are biodegradable and some non-biodegradable.
