Chapter 620 (1/2)

Fang ye said: ”of course, an ecosystem also contains many different food chains!

In addition to frogs, common beneficial agricultural animals also have various spiders. Some of them make webs in the rice field and prey on flies such as rice planthoppers and moths. Some spiders don't make webs. They hunt and prey like Rangers on the upper reaches of rice straw stems and leaves. They move rapidly, making it too late for the flies to escape!

There are dragonflies, which are carnivorous insects. They can hunt while flying. In addition to catching pests such as moths, they are also good at killing mosquitoes in rice fields!

Not only do flying mosquitoes feed on them, but the larvae of mosquitoes in the water can't escape their prey. Rice fields are an ideal habitat for dragonflies.

At present, there are no dragonflies in our rice fields, but there are frogs. Will the dragonflies be far away? They may appear in the next round of sowing! ”

The children made a burst of exclamation: ”Oh ~”

”Dragonflies can sometimes be seen near the green belt downstairs of my house!”

”When I was cutting rice just now, I saw a spider running away!”

Tang Xiaoxin dislike the way: ”I hope dragonflies make complaints about mosquitoes.”

She doesn't know why. She is very popular with mosquitoes for some reason!

Several people in the family watched her bite every time, and a bite would swell a big bag, which could not disappear for several days.

One summer vacation, I stung my mouth. My mouth was swollen like a sausage. I had an appointment with my classmates to play. My image was too humiliating to go out. I couldn't go out. I stayed at home for a week. The thief felt bad.

Fang ye said, ”there are also many creatures in the underwater world of rice fields!

For example, fish such as tamarisk and loach feed on small insects and animal and plant debris scattered in the water.

In addition to avoiding the predation of birds such as herons, they should also guard against ferocious predators in the water.

Beetles like dragon lice, also known as water turtles, are good fishermen in the water. They swim very fast!

There are so many plants and animals here. They eat, drink, grow old, die, produce feces, withered leaves, animal limbs and corpses. The ecosystem in the rice field can also deal with these ”garbage”.

For example, we may have the impression that when we eat seafood barbecue, we take a long mouthful of soup, pick it with a toothpick, and take a small mouthful of fragrant and spicy meat, right? ”

The little fat man who just shouted to eat the pot couldn't help swallowing his saliva, and the parents couldn't help laughing!

Remember the good memories of catching water turtles, loaches and snails in the fields in childhood.

”The snail is usually hidden in the mud and water. It's actually a dustman in the field and a diligent dustman in dealing with garbage!

In addition to the planktonic algae that are hard to see by human eyes in the rice field, their food will also eat the withered leaves and clean the animal bodies in time to prevent them from rotting and smelling in the water and affecting the water quality.

In this process, animals such as dragon lice will also participate, and these ”garbage” will become smaller and smaller.

Then, microorganisms such as bacteria and fungi that are difficult to see by the naked eye will complete the final finishing work, reduce organic matter into inorganic minerals, become nutrients for plant growth, and re-enter the cycle. ”

Rice, algae, duckweed!

Mosquitoes, planthoppers, moths, spiders, dragonflies!

Locusts, frogs, mice, snakes, herons!

Loach, dragon lice, snail, microorganism!
