Why do worms need microbes? Earthworms lack teeth and sufficient digestive enzymes of their own, relying instead on microorganisms to begin to rot and soften organic matter so it can be ingested, than relying on naturally occurring bacteria and fungi in their gut to digest their food. In the process of taking in this biologically active pre-digested organic matter the earthworm also ingests small particles of sand and soil, which lodge in their gizzard. As the organic matter and microbial life coating it move past this gizzard they are ground against the gritty particles lodged there and fragmented into smaller pieces, making them easier for the gut organisms to digest. Researchers have recently learned that it is not from the organic matter itself, but from the bodies of the microbial life rotting the organic matter that epigeic earthworms derive the bulk of their most vital nutrients.
