Leaves falling from trees should be:
(a) dumped in landfill areas
(b) dried and burnt
(c) used in making compost
(d) dumped near the ponds and lakes
Correct Answer: (c) used in making compost
Explanation:
Leaves falling from trees should be used in making compost. The garbage containing plant and animal wastes, and waste food, when left as such in pits or heaps, is acted upon by bacteria, fungus-like organisms, causing rotting.
Rotting leads to the formation of manure. It is the conversion of complex molecules into simple molecules that can be used by plants for growth and development. Thus, the rotting and conversion of some organic materials into manure is called composting.
It is a process in which substances are converted into manure for use in agricultural fields.
A landfill is a place in which garbage is buried under the soil in an area. On burning the dried leaves, lots of gases and pollution are produced, which is not good for the environment. If we dump the leaves near the ponds and lakes, the leaves may fall into the lakes, polluting the body of water and contaminating it.
