All these move into the drains and sewer lines which get choked and do not allow flow of water. As these are non-biodegradable, they remain as such for a long time. So to overcome this problem, we should use bags made up of cloth or jute which are biodegradable. (i) Answer the following questions : (i) Name a polymer which is biodegradable. Write the sturctures of monomers and the repeating unit. (ii) Write two uses of this polymer. (iii) Write any two values shown by Irfan.
