Answer 2

i) Composting -b) Can be used as manure for gardening.

ii) Spitting -d) It is banned in the metropolitan cities.

iii) Soil - a) It becomes polluted when waste from factories is thrown on it.

Explanation:

• Composting is the biological decomposition of the waste such as plant or food material by fungi, bacteria, worm, and other organisms. The ultimate end product of the composting is a partially decaying of the organic matters which is called humus.
• Spitting is a very bad practice as this spreads the germs which are the cause of several health problems.
• There is much waste which is produced by factories and households and by humans also that can pollute the soil. This way the soil gets polluted.
