Earthworms are decomposers that consume organic matter, so they would most likely be found in the organic horizon known as the O horizon. This horizon is composed mostly of organic litter, humus, and some minerals. The other horizons are mostly composed of mineral particles and do not contain enough organic matter to support earthworms.
