What type of feeder is an earthworm

Depth of burrows is usually up to 50 cm, but may be deeper - up to 2. In cold and dry weather, earthworms are deeper down.

Addition of Humus Organic matter dragged into soil decays gradually under the action of bacteria and fungi in moist conditions to become humus. Mixing Soil taken in at one place becomes deposited elsewhere, causing a gradual turnover in the soil. This is especially important in breaking down the distinctions "horizons" between different layers in the soil. Worms bring mainly fine soil particles upwards as well as grinding it in the "gizzard" to produce a good "tilth", partly neutralising acid soils, and taking organic matter from the surface downwards.

As the soil passes through the earthworm, the earthworm removes and processes microscopic organisms and nutrients.

Earthworms will eat both organic matter and small microorganisms. Earthworms will feed on dead grass and leaves if they are above the surface of the ground.

It is considered more common than bulk feeding because of the huge number and diversity of soil organisms that exist. Phagocytosis is the feeding mode most popular among many unicellular organisms, such as amoeba. It consists of a cell completely enveloping another cell and digesting it using a lysosome.

The phagocytes in the human immune system use phagocytosis to consume invaders such as bacteria. Most heterotrophic non-photosynthesizing unicellular organisms use phagocytosis as a way to get food.
