(a) Plastic paper, tin foil, wrappers
(b) Broken plastic toys, polythene bags, pieces of clothes
(c) Egg shells, vegetable and fruit peels and tea leaves
(d) Aluminium wrappers, plastic bags and dry leaves
Correct Answer: (c) Eggshells, vegetable and fruit peels, and tea leaves
Explanation:
Eggshells, vegetable and fruit peels, and tea leaves are good for making compost as they are organic and biodegradable wastes. Plastic wraps, tin foil, and other wrappers are non-biodegradable and hence cannot be used as compost.
The garbage containing plant and animal wastes, and waste food is used for making compost. When this garbage is left in pits or heaps is acted upon by bacteria, fungus-like organisms causing rotting which leads to the formation of manure. It is the conversion of complex molecules into simple molecules which can be used by plants for growth and development. Thus, the rotting and conversion of some organic materials into manure is called composting.
Bio composting: A mixture of organic matter, such as from leaves and manure, is composted or decayed or has been digested by organisms. This organic waste is used to improve soil structure and provide nutrients. When this type of composting is done with the help of worms, it is known as vermicomposting.
