Earthworms are known to eat a variety of substances, including dirt, leaves, and decaying organic matter. They are considered detritivores, meaning they break down dead organic matter such as plant matter, dead animals, and faeces, and play a crucial role in enriching the soil with their mucus and excretions. With an estimated 6,000 species of worms worldwide, each type of worm has unique dietary preferences based on its habitat.

What You'll Learn
Earthworms are detritivores
Earthworms do not have teeth, so they swallow their food whole. They use a lip-like flap to push the food into their mouths, after which their throat muscles lubricate it with saliva and push it down the oesophagus. They have a simple digestive system, with a straight long tube from the mouth to the anus.
Different types of earthworms have different dietary preferences. For example, composting worms, also known as red worms or red wigglers, thrive on organic waste such as fruit and vegetable peelings, coffee grounds, tea bags, grains, and eggshells. They live near the surface of the soil and prefer a diet rich in organic material, making them excellent composters. In contrast, epigeic earthworms live in leaf litter and rotting logs and feed on organic matter that is partially decayed. Anecic earthworms pull decaying plant matter into their burrows.
Earthworms also follow a chemical trail to find their food. They have a sort of mental GPS that comes into play when there is no chemical scent of food. They will surface at night to pull fallen leaves and brush into their burrows, consuming them once they soften.

They eat dirt
Earthworms are detritivores, which means they eat dead organic matter, including dirt. They are also known as 'nature's plow' because they are soil-dwelling worms that consume soil and the organic matter within it. This includes plant matter, dead animals, algae, fungi, bacteria, protozoa, nematodes, rotifers, and other microorganisms.
Earthworms eat dirt, but they are also known to consume decaying organic matter on the surface, such as leaves, brush, and other dead plant material. They help recycle organic matter and nutrients back into the soil. This makes them important decomposers, breaking down organic matter into basic nutrients for the soil.
Different types of worms have different dietary preferences, and these preferences can have significant effects on the soil and the surrounding ecosystem. For example, composting worms, also known as red worms or red wigglers, thrive on organic waste such as fruit and vegetable peelings, coffee grounds, tea bags, grains, and eggshells. They live near the surface of the soil and prefer a diet rich in organic material, making them excellent for composting.
In contrast, earthworms burrow into the soil and eat the dirt directly, consuming the organic matter within it. This helps improve soil structure as they create channels that allow air and water to penetrate more deeply. This aeration of the soil makes it more hospitable for plant roots and beneficial soil microorganisms.
One of the most beneficial byproducts of an earthworm's diet is worm castings, which are rich in nutrients like nitrogen, phosphorus, and potassium. These nutrients are essential for plant growth, making earthworms critical contributors to soil fertility and healthy ecosystems.

They eat dead animals and plants
Earthworms are detritivores, which means they eat decaying organic matter, including dead animals and plants. They are also known as decomposers, breaking down organic matter into basic nutrients for the soil. This process is crucial for recycling nutrients in the ecosystem, and earthworms play a significant role in it.
Earthworms eat a range of matter, including dirt or soil, which contains organic matter such as plant matter and dead animals, as well as algae, fungi, bacteria, protozoa, nematodes, rotifers, and other microorganisms. They swallow their food whole since they lack teeth, and they use a lip-like flap to push the food into their mouths.
Different types of worms have different dietary preferences, and these preferences can significantly impact the soil and the surrounding ecosystem. For example, composting worms, also known as red worms or red wigglers, thrive on organic waste such as fruit and vegetable peelings, coffee grounds, tea bags, grains, and eggshells. They live near the soil surface and prefer a diet rich in organic material, making them excellent for composting.
Epigeic earthworms, which live in leaf litter and rotting logs, feed on partially decayed organic matter on the surface. Anecic earthworms pull decaying plant matter into their burrows, while endogeic earthworms burrow and eat the soil itself.
Earthworms also have a unique digestive system that allows them to process the organic matter they consume. They have a long tube from their mouth to their anus, and their throat muscles lubricate the food with saliva before pushing it down the oesophagus. Earthworms also have several internal parasites due to their diet, including protozoa, nematodes, and Platyhelminthes, which can be found in various parts of their bodies.

They eat fungi
Earthworms have a varied diet, eating both plants and animals. They are often described as detritivores, consuming decaying plant and animal matter. However, recent studies have shown that earthworms may be preferential fungivores, with a particular taste for mycorrhiza, a type of fungus that grows on the roots of some plants.
Earthworms have a preference for dark-pigmented microfungi, which are often referred to as Dematiacea. These include both fruiting species, such as Cladosporium, Alternaria, and Ulocladium, and species with sterile dark mycelia. This preference may be due to the superior enzymatic capabilities of these fungi, which indicate a specific stage of decomposition where nutrient concentrations are high. Additionally, dark-pigmented fungi may be less toxic than other varieties, and earthworms may avoid chitinolytic fungi, such as Trichoderma, Penicillium, and Mortierella, as they could be digested by these fungi themselves.
The presence of earthworms in soil can significantly impact the diversity and community structure of fungi. Earthworm inoculation in fields with returned straw has been shown to accelerate straw degradation and promote the conversion of straw carbon to soil carbon. This process helps to reduce the incidence of soil-borne diseases caused by returned straw. While straw return generally increases the diversity and abundance of the fungal community, the introduction of earthworms can inhibit this expansion.
The specific food preferences of earthworms have been studied through selection experiments, offering various fungal species and observing their choices. These experiments have revealed that certain earthworm species demonstrate a preference for specific types of fungi. For example, the earthworm species Lumbricus terrestris and Aporrectodea caliginosa have shown a preference for Cladosporium cladosporioides and Mucor sp. fungi, respectively.

They have internal parasites
Earthworms are soil-dwelling invertebrates that are usually described as detritivores, meaning they eat decaying plant and animal matter. They have also been observed to eat fungi. Interestingly, earthworms have been observed to exhibit regenerative capabilities, with some species even growing replacement heads.
Earthworms have many internal parasites, including protozoa, platyhelminthes, mites, and nematodes. These parasites can be found in various parts of the worm's body, such as their blood, seminal vesicles, coelom, or intestine, and even in their cocoons. For example, the mite Histiostoma murchiei is a known parasite of earthworm cocoons.
Internal parasites are organisms that rely on a host to hatch, grow, and thrive. They use the host's body for nourishment and shelter and can cause various infections and symptoms, particularly affecting the digestive system. Intestinal parasites can cause abdominal pain, gas, nausea, and vomiting. According to the World Health Organization (WHO), approximately 25% of the world's population has an infection related to intestinal parasites, with the number reaching as high as 50% in areas with limited access to clean water and sanitation.
People can also get intestinal parasites by ingesting microscopic parasite eggs that have been passed through faeces. This can occur through consuming contaminated water or food, walking barefoot on contaminated soil, or even touching surfaces and then touching one's mouth. The larvae of some intestinal parasites can enter the body through the skin.
In conclusion, earthworms are subject to various internal parasites that can affect their health and potentially impact their populations. These parasites can also have implications for other organisms in the food chain, including humans, who can become infected with intestinal parasites through various transmission routes.
