Earthworm. It is a relatively common animal, and earthworms are generally found when cultivating farmland, and where there are earthworms, the land is relatively soft, so earthworms can give people "arable land". So people wonder how earthworms live underground, what they eat and how they reproduce?
In fact, earthworms live underground and come and go as freely as fish live in water. Some of the organic matter in the land is the food of earthworms, such as dead branches and leaves and various microorganisms.
In everyday life, people dig earthworms to feed chickens or fish for fishing. Earthworms are invertebrates.
Earthworms generally eat all kinds of dead branches and leaves in the soil, as well as microorganisms, and when they eat these foods, they will eat them together with the soil, and then absorb the nutrients from the west in the body, and excrete the indigestible things from the body. Moreover, the substances excreted by earthworms can be used to fertilize crops and flowers, so for crops, the waste discharged by earthworms also becomes a kind of nutrients and fertilizer. In rural areas, many people will catch earthworms in other places to their land to help loosen the soil.
Those naughty children often catch some earthworms to cut them in half, and after being cut in half, the earthworms can survive for a period of time, people think that the earthworms reproduce into two, but in fact this is not the case, earthworms are generally relatively small in life. Therefore, earthworms do not reproduce by cutting off their bodies.
According to the discoveries of scientists, earthworms are hermaphrodites.
To put it bluntly, an earthworm is both male and female, but he cannot reproduce his offspring by himself, and he also needs the help of another earthworm to complete it. Moreover, earthworms lay eggs for reproduction, which is equivalent to egg animals. Earthworm eggs are encased in cocoons for fertilization, and a fertilized egg has one or more embryos.
Therefore, earthworms reproduce in the above ways.

Earthworms are saprophagores, eat rotting plants or small insects in the ground, and also eat soil and gravel, earthworms reproduce sexually, hermaphrodites are very magical, they will lay eggs after mating, and the varieties are different 1 week and 3 months earthworm eggs can grow into earthworms.

Earthworms live underground, just like a fish swim in water, earthworms eat some rotten leaves and various microorganisms underground, and earthworms reproduce by laying eggs.

Earthworms are terrestrial annelids that live in the soil, are nocturnal, and feed on putrefactive organic matter, which they swallow along with the soil. Earthworms are hermaphrodites, but they cannot reproduce their own offspring with themselves, and must reproduce their offspring by laying eggs with other earthworms.

The upstairs guy may have accidentally made a typo ......Earthworms are not dioecious, but hermaphroditic, each single individual has two sets of reproductive systems, but allofertilization is required to complete sexual reproduction, because the sexual cell maturity period of a single individual will be different, so it must be mated between different individuals to complete insemination. In the case of a broken body under the action of an external force, it can be regenerated.
In addition, it has been reported that ringworms can reproduce asexually from auto-laying cells into new individuals without insemination.

Earthworms are dioecious, allofertilized, which is sexual reproduction.
Of course, earthworms can be regenerated into two or three earthworms due to accidental body breaking, which is asexual reproduction.
Asexual reproduction also includes parthenogenesis in ringworms.
This is because earthworms have a relatively high protein content, which is why they are popular with fish and are very popular foods.
Usually, when people see spiders, they wave their brooms and slap them to death, and no one says that they can quietly observe the living habits of spiders. But let's find out today! >>>More
Turn on the desk lamp, put on the earplugs, don't deliberately force yourself to resist the noise and isolate yourself from the outside world, just concentrate on the books you read, the homework you write, and forget everything after you put yourself in. I'm now completely able to watch an American drama laughing without earplugs and I'm already in another world.
