Earthworms and their relatives live anywhere there is moist soil and dead plant material. Earthworms are most abundant in rainy forest areas, but can be found in many habitats on land and in freshwater. All earthworm species need moist soil conditions to survive.

What is an earthworm's role in the environment?
Earthworms can play a variety of important roles in ecosystems. Their feeding and burrowing activities incorporate organic residues and amendments into the soil, enhancing decomposition, humus formation, nutrient cycling, and soil structural development (Mackay and Kladivko, 1985; Kladivko et al., 1986).
Which one of the following is the Anecic species?
Anecic species are the largest species of earthworms in the UK. They are darkly coloured at the head end (red or brown) and have paler tails. Anecic earthworm species include Aporrectodea longa, Aporrectodea nocturna, Lumbricus friendi and Lumbricus terrestris.
What do Endogeic worms eat?
Epigeic worms live close to the soil surface and feed on decaying plants. Endogeic worms live deeper in the soil in permanent burrows, and they feed mostly on soil and microbes.
What is worm niche?
An earthworm. As with all other organisms, these earthworms occupy a certain niche: They are both decomposers and consumers, feeding on things like decomposing remains, manure, and other small underground organisms like nematodes, bacteria, fungi, and rotifers.
How might the earthworm's color be a benefit in its natural habitat?
Earthworms digest the organic matter and excrete waste products along with any dirt that was also ingested. ... How might the earthworm's color be a benefit in its natural habitat? It's brown and so is dirt, so it helps it hide from predators. What is the function of the clitellum?
How does bacteria decompose dead plants and animals?
When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.
What is Anecic?
Filters. (of earthworms) Building deep vertical burrows and surfacing to feed. adjective.
Are earthworms decomposers?
Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.
Are earthworms predators or prey?
Earthworms are preyed upon by many species of birds (e.g. robins, starlings, thrushes, gulls, crows), snakes, wood turtles, mammals (e.g. bears, boars, foxes, hedgehogs, pigs, moles) and invertebrates (e.g. ants, flatworms, ground beetles and other beetles, snails, spiders, and slugs).
What are Endogeic earthworms?
Soil Dwelling (Endogeic): Endogeic worms are soil dwelling worms that build complex horizontal burrows in the upper layers of soil and rarely come to the surface. Adult endogeic worms are normally small and unpigmented (not colored). Endogeic worms feed on soil, which helps to mix minerals and air into the soil.
What does Endogeic mean?
Epigeic is Greek for 'upon the earth', endogeic means 'within the earth' and anecic is Greek for 'out of the earth'. ... Soil-dwelling earthworms fall into three main niche groupings: epigeic, endogeic and anecic.
Do worms feel pain?
But a team of Swedish researchers has uncovered evidence that worms do indeed feel pain, and that worms have developed a chemical system similar to that of human beings to protect themselves from it. The Swedish scientists, J.
Is soil the earthworms niche?
Is soil an earthworms niche? ... They aerate the soil, fertilize it with their waste and feed on leaves, dirt and other organic matter.
Is earthworm a herbivore?
In Earthworms, by Sims and Gerard (1985), most earthworms are described as omnivorous (eating plants and animals). However they better described as detritivores (eating decaying plant and animal matter). ... There are studies to suggest they eat a fungus called mycorrhiza which grows on the roots of some plants.
What are earthworms predators?
Earthworms have some natural enemies such as ants, centipedes, birds, snakes, toads, carabid beetles, and nematodes.
