Answer 2

material like plastic can be decomposed by bacteria, mortal, physical activites such as heat and pressure. (d)All the above

Explanation:

• Usually, plastics are not easily decomposing material because it's not organic substance. Normally plastics can not easily be decayed by either microorganisms or by landfill it would take many years.
• However, genetically modified bacteria like Ideonella sakaiensis are able to eat some kind of plastic. bacteria like pseudomonas are massively active in the degrading $20.54\%$ of polythene.
• The higher pressure and heat for constant time would increase the speed of decay.
• when in the sea the breakdown is due to sunlight, oxidation, and by animals nibbling on plastic.
