Why do earthworms keep dying on the ground?

Earthworms breathe with **, the soil is wet and sealed, and the air permeability is poor! So earthworms often burrow out of the ground. In addition, after heavy rain, the soil moisture content increases greatly, blocking the capillary pores in the soil, and the earthworms have to go to the ground to breathe when the oxygen is insufficient.

The oxygen content in the soil is low due to the rain, and the earthworms go to the ground where there is plenty of oxygen. Earthworms prefer to live in dark, damp soil. If it rains and rainwater flows into the soil, the voids in the soil are occupied by rainwater, and it is difficult for earthworms to adapt to this environment, so after the rain, earthworms will burrow out of the soil and go to the ground to breathe.

Oxygen in the cracks of the soil is usually dissolved in the mucus on the surface of the earthworm**. But after heavy rain, the rainwater fills the cracks in the soil, and the earthworms can no longer breathe and have to burrow out of the ground. In sunny and dry weather, earthworms do not dare to come out, and once the mucus on the surface of the ** surface evaporates in the dry air, the earthworms will suffocate to death.

Earthworms crawling out of the ground may be due to insufficient oxygen levels in the soil. When the weather is hot or rainy, the soil has more moisture content, and the earthworm's ** cannot breathe after being wrapped in water, so it will crawl out of the ground to breathe oxygen.

Earthworms live in the dark soil all year round, afraid of the light, afraid of the sun and blue light, and they spend their ordinary and dark life in the dark soil. Earthworms generally prefer to live in moist, loose and organic soil, especially in fertile gardens, vegetable gardens, cultivated fields, ditches, rivers, ponds, canals, and sewers, garbage heaps, and water tanks near canteens.

Earthworms prefer a quiet environment to a noisy environment. Earthworms are more afraid of pesticides, and it is difficult to find earthworms in places where pesticides are excessive. In other words, the environment in this park is quite good, quite suitable for the survival of earthworms.

However, on a rainy day, they managed to crawl out of the soil, but they were faced with the giant feet that stepped on them at any time, leaving them with no bones under a blow.

Summary. Earthworms crawling out of the ground may be due to insufficient oxygen levels in the soil.

Why do earthworms crawl out of the soil and die on the ground?

Earthworms crawling out of the ground may be due to insufficient oxygen levels in the soil.

The reason why the earthworm crawls out of the soil and dies on the ground is that the earthworm breathes by **, if it rains, the rain fills the soil gaps, and the earthworm's ** cannot breathe after being wrapped in water, so it will crawl out of the ground to breathe oxygen. Once the mucus on the surface evaporates in dry air, the earthworm suffocates to death.
