The earthworm obviously has no hands, so what does it do to dig in the dirt?

Earthworm. The reason for loosening the soil is not only because earthworms need to be kept moist, so they drill around in the soil.

Most of the earthworm's body is bodily fluid, so it is easy to die due to lack of water, which has been mentioned in why earthworms can still live when cut in half, so earthworms need to live in 10-30 cm of soil underground, because the deeper the soil, the better the water retention, so the earthworms will keep drilling in the soil all the time, so that the soil will become more loose.

In addition, earthworm excrement can also make the soil fertile, and we often see some very fine fine sand around earthworms, which is earthworm excrement. Because there are many animal and plant carcasses in the soil, after the earthworm swallows the soil, the organic matter is fully digested, and then the discharged soil is rubbed by the muscles in the earthworm gizzard, and the particles become very fine. Moreover, the sandy soil digested by earthworms will be rich in a lot of nutrients, which can make the soil more fertile, and with the characteristics of earthworms drilling into the soil, the soil will become softer and softer with the help of earthworms, and the soil quality will be better and better.

The special digestion ability of earthworms can also effectively decompose organic waste, because it will secrete various enzymes, so many countries use earthworms to deal with garbage, such as Los Angeles, there are special earthworm farms, 1 million earthworms per month can process tons of garbage, and Ontario, Canada.

Earthworms are also farmed, 20 tonnes of garbage are processed every day, and the manure produced is still used on the farm.

In addition, earthworms can also be used as food, although it looks disgusting, but there are records of eating earthworms since ancient times in China, most of them are coastal minorities.

They chop up the earthworms and mix them into the chaos filling, which makes the ravioli more delicious, because the earthworms contain glutamate in their bodies.

And earthworms are also often used for **, with a lot of pharmacological functions, it is said that earthworms can extract delotonin and xanthine in the body.

Antihistamine. and other ingredients. In addition, earthworms can be used as the best feed for farmed fish and livestock, which can make the animals grow better.

Earthworms rely on the wriggling of their bodies to make the soil soft, and then burrow through the soil.

Earthworms rely on the wriggling of their heads to loosen the soil, and then add the swing of their bodies to reach the digging ground.

It relies entirely on its body to excavate the soil, and this is the only way it can do it, and its body structure is very special.

The ancestors of earthworms had eyes, because most earthworms live underground and have no light, so they can't see with their eyes, so after the evolution of nature, the eyes of earthworms gradually degenerate. Although the eyes are degenerate, there are many cells on the earthworm** that can sense light, which can replace the eyes. If you put an earthworm in a place with strong light, it will crawl in the direction of low light.

It is because it has special cell tissues on its body that can discern directions, and it likes to live in dark and damp places.

Earthworms don't have eyes, they have photoreceptor cells on their bodies, so they can tell the difference between bright and dark places.

Aren't earthworms in the soil?

Once upon a time, crickets, ants, and earthworms lived in the same village and were good friends. The road in the village was not easy to walk, so they got together and decided to repair the road.

The earthworm said, "I'm so tired from building roads that I don't want to repair them." The ant asked again

After the road is repaired, won't you go? The earthworm stretched and said lazily, "No, no, absolutely not."

When the ants saw the earthworm like this, they said, "What if you are gone?" "If I go this way, you'll throw me in a hole.

The earthworm yawned. After everyone's efforts, the road was finally repaired. Ants and crickets are happy on the road.

The earthworm couldn't help but climb onto the road at this time. However, it was soon seen by two ants, who, without saying a word, caught it and threw it into the hole as the earthworm said. The earthworm lay quietly in the hole, regretting it in his heart, and said to himself

It would have been nice if I had built roads too! It thought about it, and was so sad that it shed the golden bean.

Since then, earthworms no longer dare to go to the road, and always drill in the soil. However, the earthworm has become very industrious, and every day, it helps the crops loosen the soil.

Oh, by the way, if you see an earthworm, remember to tell it that ants and crickets have long agreed to go that way!

AnswerEarthworms are ectotherms, and their body temperature changes with the change in the temperature of the outside environment. Therefore, the dependence of earthworms on the environment is generally more significant than that of homeothermic animals, and the ambient temperature not only affects the body temperature and activity of earthworms, but also affects the metabolism, growth and development and reproduction of earthworms, and the temperature also has a greater impact on other living conditions, thus indirectly affecting earthworms. Therefore, temperature is one of the most important living conditions for earthworms.

It also needs to breathe air, especially on rainy days, and even more so from the dirt.

Sometimes there are fish in the pond after a while after the rain, and this is the same reason. The main thing is that the eggs of these animals (all of which are relatively small) migrate with wind and rain.

No, earthworms are not naturally formed, earthworms are a general term for oligochaetes of the phylum Annelids. In the scientific classification, they belong to the order Unichovida. Answer: The two sides of the body are symmetrical, with the phenomenon of segmentation; There are no bones and the body surface is covered with a thin cuticle with pigment.

With the exception of the first two segments of the body, the rest of the segments have bristles. Hermaphroditic, allogeneic fertilization, the production of egg cocoons through the ring belt during reproduction, and the reproduction of the next generation. There are more than 200 species of earthworms, which were called the most valuable animals on earth by biologist Charles Darwin in 1837.

Because earthworms are most effective in the soil.

I think it's the bacteria in the soil that evolve slowly! Ha ha.
