B) Leech
C) Snail
D) Beetle

Answer 1

A compost is generally organic matters that has been decomposed. In most cases it is made up of leaves, shredded leaves or kitchen scraps. Composting can be done using various agents and with respect to this vermicompost is a composting procedure that is done with the help of worms.

Complete answer:
To define vermicomposting more elaborately, it is the process of decomposition of vegetable, food waste or other organic material using the help of various species of worms such as red wigglers, white worms or other earthworms. The end product produced by the breakdown of the organic material is called the vermicast. Vermicasts contain high levels of nutrients and reduced levels of contaminants. Being rich in nutrients vermicasts are important sources of organic fertilizers and soil conditioners. Worm castings also contain worm mucus that prevent nutrients from getting washed away from the soil as a result of flow of water. The process of vermicomposting not only increases the soil quality but also improves soil aeration and water holding capacity which in turn improves plant growth thus enhancing crop yield.

Hence the correct answer is option (A) Earthworm.

Note: Vermicomposting thus is an important process as it not only improves soil quality but also plant growth. It also reduces the greenhouse gases emission thus helping in improving environmental conditions as well.
