Answer:
Compost is the end product formed by the biodegradation of organic matter such as yard waste and food waste. This is done by microorganisms, such as bacteria. Yeast also helps in this process.
Vermicompost is the end-product formed by the degradation of organic matter. This process is done only by worms, such as red wrigglers, white worms and earthworms.
