Anonymous users2024-02-13What environment do earthworms live in? How do you distinguish the head and tail of an earthworm? How do earthworms breathe? How do earthworms move?
Answer: Earthworms are suitable for burrowing in humus-rich soils with a certain temperature and humidity, little change in temperature difference.
Earthworms do not have a respiratory system and rely on mucus-secreting moist body walls for breathing. Earthworms have capillaries on the body wall, and the blood contains hemoglobin, which can carry oxygen.
The animal body is segmented, which can make the body move flexibly, freely and easily. The body segments of earthworms have the above functions. The ends of the earthworm bristles can be in contact with the rough surface of the surrounding environment to support and coordinate with the ring and longitudinal muscles to complete the movement.

Anonymous users2024-02-11Mitochondria are aerobic.
Earthworms exchange gases on the surface of their bodies. Oxygen dissolves in the moist membrane on the surface of the body, then penetrates into the corneum membrane and epithelium, reaches the microvascular plexus, and is transported to the naming part of the body by the hemoglobin in the plasma combined with oxygen. The epithelium of earthworms secretes mucus, and the dorsal pores drain body cavity fluid, which often keeps the body surface moist and facilitates respiration.
It has been suggested that earthworms can also breathe in water or perform panoxygen.

Anonymous users2024-02-091. Earthworms are aerobic organisms, and generally when it rains, they will see earthworms crawling out of the soil because the rain seals the cavities in the soil, so it has to come up to breathe air.
2. And it is also a decomposer, because decomposers are heterotrophs, they decompose the residues of animals and plants, feces and various complex organic compounds, absorb certain decomposition products, and finally can decompose organic matter into simple inorganic substances, and these inorganic substances can be reused by autotrophs after participating in the material cycle.
3. Earthworm milling has been excavated for feeding, digestion, excretion of earthworm feces), secretion of mucus) and burrowing and other activities contribute to the material cycle and energy transfer of soil processes, and is one of the soil nucleus vertebrate groups that have an important impact on many processes that determine soil fertility, mainly earthworms, mites and ants, and is known as ecosystem engineers.

Anonymous users2024-02-08The body wall of the earthworm is densely covered with capillaries, and the oxygen in the air first dissolves in the mucus on the body surface, then seeps into the body wall, and then enters the capillaries of the body wall. Carbon dioxide in the body is also excreted from the body surface through the capillaries of the body wall, and the breathing of earthworms depends on the body wall that can separate the state and secrete mucus and keep it moist at all times.
Earthworms, also known as earth dragons, are terrestrial invertebrates of the phylum Annelids.
Earthworm is one of the annelids, there are more than 3,000 traces of earthworms in the world, and there are more than 200 species in China. There are ringworms, Aisheng worms, heterolip worms, Dura, etc., which are widely distributed throughout the country.
Earthworms are rich in nutrition, rapid reproduction, miscellaneous diets, and high yield in artificial breeding. Good economic benefits. Earthworms can be used as a valuable medicine** for many diseases, and can also be used as high-protein food and feed.
Earthworms dig holes to loosen the soil, decompose organic matter, create good conditions for the growth and reproduction of soil microorganisms, and play a special role in soil improvement, elimination of pollution, protection of the ecological environment, material cycle, biodiversity, etc.
Breathe against the walls of your body.
The body of the earthworm is composed of many body segments, which are annelids, and the ventral surface of the body has bristles to assist in movement, and earthworms do not have special respiratory organs, they rely on the body wall to exchange gases with the outside world. >>>More
Electrocuting wild earthworms is illegal. Earthworms can loosen the soil, increase the organic matter of the soil and improve the soil structure, we are now mainly alkaline soil, can reduce the alkalinity, become neutral, increase the effective phosphorus and potassium content in the soil, suitable for the growth of crops, earthworm manure is also a good nutrient, it is different from other fertilizers, it is odorless and tasteless, has good water absorption and permeability, is conducive to plant absorption, respiration. Soil is a conductor of water, and where electricity passes, it is difficult for some small microorganisms to survive, which greatly reduces the biodiversity of the soil. >>>More

If you don't eat it, the earthworm eats the rhizome of the plant, and the soil is swallowed together while eating, and it will be excreted, so when we dissect the earthworm, he has a stomach full of dirt.
