Why do earthworms climb trees on rainy days?

It wants to breathe, the earthworm breathes by **, and the rain will block the breathing hole. That's why you have to come out and breathe. But this will be accidentally trampled to death by us humans.

Because of the lack of oxygen in the soil on rainy days.

As the saying goes, "Earthworms climb up, and the rain is like hemp." Earthworms come out of their holes – The ground is moist and soft, and earthworms will crawl out of the ground, indicating that it is going to rain.

Natural terrestrial earthworms generally prefer to live in moist, loose and organic-rich soils, especially in fertile gardens, vegetable gardens, cultivated fields, ditches, rivers, ponds, canals, and sewers, garbage heaps, and water tanks near canteens.

Earthworms need good ventilation to replenish oxygen and expel carbon dioxide. It is particularly sensitive to ammonia, flue gas, etc. When ammonia exceeds 17 parts per million, it will cause an increase in earthworm mucus secretion and the death of clusters.

The main harmful gases in the flue gas are sulfur dioxide, carbon monoxide, methane, etc. When artificially breeding earthworms, in order to keep warm, the furnace in the house must not leak flue gas.

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. If the breeding bed is flooded, most earthworms will flee immediately, and if they can't escape, they will show edema and reduced vitality.

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 rely on the oxygen diffused into the soil by the atmosphere for respiration, and the better the soil is aerated the earthworms can be better metabolized. On rainy days, the rain fills the pores of the soil, so it will be difficult for the earthworms to breathe, which causes a large number of earthworms to crawl out of the ground to breathe air.

Earthworms rely on the oxygen diffused into the soil by the atmosphere for respiration, and the better the soil aeration, the more vigorous its metabolism is, not only producing more vermicoons, but also shortening the maturity period.
