What kind of food web are earthworms part of?
Earthworms basically get their nutrition from fungi and bacteria. In turn, earthworms promote the activity of these organisms by shredding and increasing the surface area of organic matter so that it is more available to these small organisms.
Earthworms are invertebrates, which means they do not have a backbone. In fact, they have no bones at all. The presence of earthworms in soil influence the presence of other soil-inhabiting invertebrates by changing the amount and distribution of organic matter and microbial populations.
Earthworms have few invertebrate enemies. Their main predators are a wide range of birds and mammals that prey upon them at the soil surface. But they are attacked by some insects, such as ants.
