Enumerate in brief about the Earthworms

There are several species of earthworms, having slender cylindrical bodies with varying diameters. These organisms ingest the dead organic tissues in soil along with the soil material. The mineral soil is digested, and excreted as granular soil aggregates richer in bacteria and mineral nutrients. These organisms only transform the food so as to be more beneficial for the higher plants and are more abundant in soils which are moist, have high organic matter and undecomposed plant residues.  They are more common in fine textured neutral soils with high reserves of lime than in the coarse sandy soils.
