Answer 1

Answer:

3 option is the best way to dispose leaves

Answer 2

The best way to dispose of these leaves is 3. Put the leaves in a pit to get compost.

• When the leaves are put in a pit to obtain compost, it not only disposes of the leaves but also makes some useful manure.
• Dried leaves make a good composting raw material as it contains carbon.
• This manure can be used as fertilizer as it provides nutrients to the soil.

1. Burn the leaves outside the school campus.

Burning is not too good of a method as it causes air pollution and no useful product is obtained.

2. Throw the leaves in a nearby water body.

This method will pollute the nearby water body.

4. Let the leaves scattered on the school campus.

This will make the campus dirty, and even spread illness.
