Im sorry to say that I tgthi there is some mistake in the question. There is no such word as "dcomposting". Please upload the correct version of the question.
Incase if the question was difference between composting and vcomposting, I m providing anwer to it below
Composting is the purposeful biodegradation of organic matter, such as yard and food waste. The decomposition is performed by micro-organisms, mostly bacteria, but also yeasts and fungi.
Vermicompost, or Vcompost, is the heterogenous mixture of decomposing vegetable or food waste, bedding materials, and pure vermicast produced during the course of normal vermiculture operations. (Vermicomposting uses worms. Vermis is Latin for worms).
If you intended to ask a different question you can upload it. I will be happy to answer your doubt.
