Q.What is vermicomposting? Explain briefly how earthworms are used in this process and mention one advantage it has over ordinary composting.

Vermicomposting is a technique for managing biodegradable waste in which specific species of earthworms -- commonly red wiggler earthworms -- are introduced into a bed of organic waste. As the earthworms feed on the waste and pass it through their digestive systems, they accelerate its decomposition considerably compared with ordinary (earthworm-free) composting, and produce a particularly fine, nutrient-dense product called vermicompost, along with earthworm castings that further enrich the soil. One clear advantage of vermicomposting over ordinary composting is speed: the earthworms' digestive action breaks down organic matter considerably faster than microbial decomposition alone. It is also attractive at a househol …
