Yes, in a sense. As worms break down organic matter, they produce waste material called vermicast. This is also known as worm castings, worm humus or worm manure. These worm castings, or waste materials, are particularly rich in nitrogen, phosphate, calcium, and magnesium, and are sold in combination with other compost materials for fertilisation purposes. Basically, an earthworm is just one big digestive system. Organic matter is ingested through the front end, works its way through the worm's body, and is excreted at the back.
