Answer 1

Answer:

hope it's useful for U

Explanation:

Vermicompost enhances plant growth, suppresses disease in plants, increases porosity and microbial activity in soil, and improves water retention and aeration. Vermicompost also benefits the environment by reducing the need for chemical fertilizers and decreasing the amount of waste going to landfills

When water is used once and is no longer fit for human consumption or any other use, it is considered to be liquid waste . Wastewater can be sub categorised as industrial and domestic.

Industrial wastewater is generated by manufacturing processes and is difficult to treat.

Domestic wastewater includes water discharged from homes, commercial complexes, hotels, and educational institutions.

Answer 2

1. the use of earthworms to convert organic waste into fertilizer is called vermicomposting. Vermicompost enhances plant growth, suppresses disease in plants, increases porosity and microbial activity in soil, and improves water retention and aeration. Vermicompost also benefits the environment by reducing the need for chemical fertilizers and decreasing the amount of waste going to landfills.
2. The non-degradable waste is usually thrown in the local 'nullah'(ditches), where it meets some stream and flows on. You will also commonly find waste dumps on the outskirts of the village, like some ponds filled with litter. It is usually carried on into the sea, or is cleared by the municipal corporation if the water is about to enter some town/ city. The landfills may be occasionally cleared by the municipal authorities, like before monsoons (to avoid disease). More commonly, the garbage is burned up.
