Answer 2

Answer:

1. Vermicomposting is a method in which earthworms are used to convert the organic wastes into compost, which is a good fertilizer for plants. It increases the soil fertility. Manure is the organic matter mainly animal feces and straw. It adds nutrients (nitrogen) in the soil, which increases the soil fertility.
