What is the best way to measure the length of an earthworm?

Ruler and string.

Earthworms can loosen the soil and produce manure to fertilize the fields. In the development of the aquaculture industry, earthworm farming has become an indispensable source of protein feed. Pigs, chickens, ducks and some specialty farming will require a large amount of high-protein feed. Due to the low cost and high output efficiency of earthworm farming, earthworm farming will be one of the key aquaculture projects recommended in the future.

Earthworms can improve soil fertility. When earthworms eat soil and organic matter containing microorganisms, as the food is digested in the digestive tract, certain microorganisms also multiply in large numbers, often increasing at an exponential rate from the front to the back of the digestive tract of the earthworms. In this way, the number of microorganisms in the feces discharged by earthworms is more than 10 times that in the ambient soil, and there are more microorganisms in the soil.

Earthworm Introduction:

Earthworms, also known as earthworms, are terrestrial invertebrates of the class Oligochaeta of the phylum Annelida. There are more than 3,000 species of earthworms in the world, and more than 200 species in my country. The species widely distributed in China include Pheretima annularis, Eisenia fetida, Heterolipodium duratum, etc. Earthworms are rich in nutrition, reproduce quickly, have a variety of diets, and have high yields and good economic benefits from artificial breeding.

Earthworms can be used as precious medicine to treat a variety of diseases, and can also be used as high-protein food and feed. Earthworms dig holes to loosen the soil, decompose organic matter, and create good conditions for the growth and reproduction of soil microorganisms. They play a special role in soil improvement, pollution elimination, ecological environment protection, material circulation, biodiversity, etc. Many countries use earthworms to treat domestic garbage and organic waste and purify sewage.

Are earthworms decomposers?

Earthworms are decomposers.

Earthworms are saprophagous animals that can decompose organic matter in the ecosystem into inorganic matter such as carbon dioxide, water and inorganic salts, which are then reused by green plants. Therefore, earthworms are decomposers in the ecosystem.

Decomposer Profile:

Decomposers include bacteria and fungi, strictly speaking saprophytic bacteria and fungi, such as saprophytic microorganisms, and saprophytic animals, such as earthworms and fly larvae. Saprophytes mainly feed on lifeless, decaying animal and plant remains, decomposing organic matter to produce carbon dioxide, water, and inorganic salts. Consumers are animals that cannot photosynthesize and must feed on readily available organic matter.
