Why do earthworms and ants come out after rain?

Because after the rain, you can go out and play.

Earthworms breathe with moist body walls, breathing oxygen in the air After the rain, the oxygen in the soil crevices is squeezed out, and the oxygen in the soil is reduced, and the earthworms cannot breathe in the soil, and the earthworms have to burrow out of the ground in order to breathe Therefore, the earthworms have to climb to the ground after the rain because the air in the soil is squeezed out after the rain and there is a lack of oxygen, and the earthworms have to climb to the ground in order to breathe

So the answer is: earthworms have to crawl to the ground in order to breathe

Once upon a time, crickets, ants, and earthworms were good friends. They all live in the same village, and the roads in the village are potholed and difficult to walk. One day, the crickets and ants discussed together and decided to mobilize everyone to repair the road.

They do what they say, mowing the grass, digging the soil, mating the road, and doing it lively. However, their good friend earthworm has not come to participate in everyone's road repair work, and the ants want their good friend earthworm to participate in it, so they quietly come to earthworm and say, "Brother earthworm, why don't you help us build the road?"

The earthworm said, "I'm afraid of being tired, so I won't do it." ”

The ant said, "Then you won't walk anymore?" ”

The earthworm stretched and said lazily, "If you don't go, you won't go!" What's the big deal! ”

When the ants saw the earthworm like this, they were also angry, and they said, "What if you leave?" ”

If you see me gone, arrest me. Earthworm said.

The road was finally repaired. Crickets and ants are happily running around the road. The earthworm was very envious and also quietly climbed onto the road. But as soon as it climbed up, it was spotted by ants. The ants unceremoniously caught the earthworm and carried it into the hole.

From then on, the earthworm no longer dared to go to the road, so it could only walk in the dirt. If it accidentally walks on the road, it will be caught by ants. Until now.

The reasons why earthworms climb onto the ground after a rain are as follows:

Because there are many voids in the soil, water is usually adsorbed around the soil particles, and air is full of the voids; After heavy rain, the soil voids are filled with water, which squeezes out the air, causing a decrease in the amount of dissolved oxygen in the water, so earthworms come out of their holes.

Earthworms live in moist soil, and cannot be drilled if the body surface is dry, and earthworms breathe through the body surface, and the body surface cannot carry out gas exchange without water.

Earthworms climb to the ground after rain because the air in the soil is squeezed out after rain and there is a lack of oxygen, so earthworms have to climb to the ground in order to breathe.
