What is the main food source of worms?

The main food source of worms, particularly earthworms, consists of organic matter such as decaying leaves, dead plants, and other decomposing organic material in the soil. They consume this matter as they burrow through the soil, breaking it down and enriching the soil with nutrients. Additionally, they may feed on microorganisms present in the organic matter, aiding in the decomposition process. This diet is essential for their survival and plays a crucial role in soil health and fertility.
