What s going on with earthworms crawling onto the pavement?

There can be several reasons why earthworms can climb onto the pavement:

1.Insufficient oxygen in the soil: Earthworms use ** for respiration, and when the oxygen content in the soil is insufficient, earthworms cannot survive underground, so they will crawl out of the ground to breathe oxygen.

This condition is common after rain or when the oxygen in the soil is flooded with water, causing earthworms to not live properly.

2.Over-moist soil: When the soil is over-moist, the earthworm's ** is encapsulated in water and cannot carry out gas exchange, so it needs to climb to the surface to breathe oxygen. This condition is common when the soil is overly moist after continuous heavy rain.

3.Soil hypoxia: In some cases, the amount of oxygen in the soil may be insufficient, resulting in earthworms not being able to survive underground. This condition may be due to the presence of too much organic matter or nitrogen compounds in the soil, which consume large amounts of oxygen when they decompose.

4.Escape the elevated amount of nitrogenous waste in the soil: When the concentration of nitrogenous waste in the soil increases, earthworms may crawl out of the soil to avoid these harmful substances.

This condition is common in the soil after soaking, as the moisture dissolves the nitrogenous waste in the soil, increasing the concentration of nitrogenous waste in the soil.

In conclusion, earthworms crawl onto the road usually due to the adverse effects of the soil environment on their lives, and they need to find more suitable living conditions.

Come on you, what's the matter with the earthworm crawling onto the pavement? I think earthworms crawl on the road because they want to lie on the road and bask in the sun, so earthworms also like the sun, so after staying in the soil for a long time, she also wants to bask in the sun, so she feels very warm, right? I think earthworms just crawl out on the road just to bask in the sun, so animals also have a sense of animals, so they feel like they are basking in the sun on the road, and they are very good.

Because of the large amount of rain in the soil, the oxygen content of the soil decreases, and the earthworms need to go outside to breathe fresh air.

Although earthworms prefer humid environments, many terrestrial earthworms can survive for a long time in a completely flooded environment. But they never choose and inhabit flooded soil.

Worms are annelids that breathe with their body walls and breathe oxygen from the air. After heavy rain, there is too much water in the soil, and the rain squeezes out the oxygen in the soil crevices, and the oxygen is insufficient, and the earthworms cannot breathe in the soil, so the earthworms come to the ground to breathe in order to breathe. 【Answer】Solution:

Earthworms breathe on a moist body surface, and their body walls are densely covered with capillaries, and the oxygen in the soil 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 earthworm's breathing depends on the body wall that can secrete mucus and always keep it moist. So the answer is:

The rain chokes the cracks in the soil, and the earthworms don't get enough oxygen, so they burrow out of the soil and onto the ground.

It should be the reason for the rain.

Because of the large amount of rain in the soil, the oxygen content of the soil decreases, and earthworms need to go outside to breathe fresh air. But they never choose and inhabit flooded soil.

Earthworms crawl out of the ground to dry places in order to breathe, and some are unlucky enough to climb onto concrete pavements or tiles, and then when the sun comes out, they get sunburned to death.

Economic value. 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 burrows to loosen the soil and decompose organic matter.

Create good conditions for the growth and reproduction of soil microorganisms, play a special role in soil improvement, eliminate pollution, protect the ecological environment, play a special role in material cycle, biodiversity, etc.

The reasons why earthworms crawl out are complex, and there are many reasons, most of which are affected by the climate. Earthworms rely on ** to breathe, the most common is in continuous rainy weather, when the water content of the ground is high, the earthworm will crawl out of the ground if the oxygen supply is insufficient; Secondly, it is affected by the number of earthworms themselves, the capacity of the soil is limited, and if the number of earthworms is too large, some earthworms will also escape; In addition, it is the influence of external pollutants, and if there are drugs that seep into the soil, it will also cause earthworms to crawl out.

There are many wonderful things in nature, some of which we understand, but there are also some that people don't understand, and I also maintain a curious heart about animals in nature, so I usually prefer that kind of small, soft animals, because they look particularly cute, such as earthworms.

Earthworms are very cute little creatures, and some children will keep them at home. Whenever it rains.

Do you also find earthworms burrowing out of the soil and running to the ground, so why do earthworms climb onto the road after rain? What are they doing?

Many people think that earthworms burrow into the ground, and they must not breathe oxygen underneath, but in fact, this is not right, earthworms also need oxygen. The reason why earthworms climb onto the road after the rain is because after the rain, the voids in the soil are filled with water, and the air is squeezed out, and the dissolved oxygen content in the soil is very small, and the earthworm's breathing becomes very difficult, so the earthworms will climb onto the road after the rain.

Earthworms are very cute little creatures, and they are beneficial insects to humans.

Because it can loosen the soil, it is a very good help for some flowers and trees. After the rain, the earthworms ran onto the road one after another, because there was no large amount of oxygen in the soil after the rain, and the earthworms were not enough to breathe, so they could only run onto the road. Earthworms run to the road to breathe, earthworms use their own external ** to breathe, although earthworms live in a relatively humid place, but if there is too much water in the soil and not too much oxygen, then the earthworm may die if it does not crawl out of the soil to the road in time.

So we can know that the reason why earthworms climb onto the road after rain is because there is too much water in the soil and there is not a lot of oxygen, which is not enough for earthworms to breathe. This is also a kind of life instinct of earthworms, just like us in the water, if there is a lack of oxygen in the water, we will swim to the shore and find a way to escape. What are your thoughts on this?

Because the rain prevents the earthworms from breathing underneath, they need to climb onto the road and breathe.

Mainly for breathing. After the rain, the amount of oxygen in the soil is greatly reduced, and the earthworms will run outside to breathe.

This allows you to breathe better, and there is more rain in the soil and less oxygen, which is why you will climb to the road surface.

Because earthworms come out when it rains.

Earthworms on the road are a phenomenon that is going to rain.

As the agricultural proverb goes, "Earthworms climb the road, and the rain is like hemp." These phenomena illustrate the impact of the environment on living things. The reason why earthworms crawl out is mainly due to the weather.

Earthworms like moisture and rely on ** to breathe. When the soil is soft, there are gaps between the particles, and the earthworm does not have to breathe hard. Once there is continuous rainy weather, the rainwater seeps into the soil, the soil moisture content becomes high, the air exchange under the soil is difficult, and the earthworm will not supply enough oxygen, it will drill up to breathe, and the earthworm will crawl out of the ground in groups.

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 species of earthworms in the world, and there are more than 200 species in China. There are ringworms, Aisheng worms, heterolip worms, dura worms and other varieties widely distributed throughout the country.
