There is a food chain in nature, because living things have a relationship between eating and being eaten. There are "weak" and "strong" members in our family, thus forming my unique "food chain".
At home, my father has supreme power, and my mother is my "boss". I have to obey her instructions in everything. I am my brother's "leader" and lead him on the right path. This level-by-level relationship has brought many interesting things to my family.
Once, when I came back from class, I was bored to see my brother playing computer, so I went over and said, "Brother, I will teach you how to take the right path in life now!" " Stop playing computer and read more books! Study hard and make progress every day. "I drove my brother away, but I sat in front of the computer and enjoyed myself. Not long after, I heard my mother open the door and thought, it's over, the "boss" is back, and it's over for her to see that I don't study hard. She teaches people, but she has a "golden mouth and jade words"! So I quickly put oil on my feet-I ran away and sat at my desk pretending to study hard. After my mother came in, she was also addicted to the internet, watching her TV series, news and novels ... My mother was so fascinated that she forgot the time to cook. I reminded her: "Boss, you seem to have forgotten one thing. When grandpa comes back ("grandpa" is a respectful name for dad) and sees that you haven't done it yet, you will be furious and we will all be criticized! " Mom wants to sprint to the kitchen and become her "cook". Just then, as soon as my mother opened fire and prepared to cook, the "master" came back. After dinner, my father also held the computer and couldn't put it down. The younger brother ran to his father and stared at him with "sparkling" tears, begging him to let him play computer for a while. Dad had no choice but to "give up". I gloated over it. Ha! I went there again ... and then my parents came. ...
My brother is afraid of me, and I am afraid of my mother. My mom wants to make way for my dad, and my dad wants to follow my brother. This is my family's food chain. How's it going? Is it interesting?
2. The composition of food chain When I was in the fifth grade, I once learned an article called Snakes and Crops.
At that time, I learned a word "food chain", which was completely strange to me at that time. According to data, the concept of "food chain" was first put forward by American scientist Lin Deman. When he was studying lakes, he came across a proverb from China, which was "eat small fish, a big fish, eats shrimp and shrimp eats sludge".
He was inspired by it and put forward the concept of "food chain". So, what is the food chain? Huxley, a famous British scientist, once told a humorous story.
He said: "British cats are mainly fed by old ladies, so the strength of the British navy should be attributed to British cat owners." Where do you start? Clover is rich in England, which is the main feed for cattle.
Wild bees can effectively pollinate the dark flowers of clover. Clover can flourish mainly because of wild bees.
However, voles like to eat honey and larvae of wild bees, which affects the pollination of clover. Scholars have found that there are more wild beehives near the English countryside than anywhere else, because there are many cats in the village.
Cats eat voles, so clover thrives there, providing rich feed for cattle. Clover is the staple food of cattle, and the staple food of British navy is canned beef.
So clover contacted the British Navy again. Therefore, cows eat clover, wild bees pollinate clover, voles eat honey and larvae of wild bees, and cats eat voles. That cat is a great hero who makes clover flourish.
From this perspective, Britain has a navy that dominates the sea. Finally, it should be attributed to the cat, and further, it should be attributed to the lady who owns the cat. How amazing and interesting the food chain is! Although Huxley's words are humorous, they profoundly and vividly illustrate an important concept in ecology-food chain.
Now, you should know what food chain is! In an ecosystem, all kinds of creatures are connected by food relations. One kind of organism feeds on another kind of organism, and the other kind feeds on the third kind of organism ... and they form a food chain, which is called food chain. The food chain often begins with plants and ends with fierce carnivores.
The food chain is a food path that connects different species in the community. Energy and nutrients in the food chain are transferred between different organisms.
This is called the food chain. Science is everywhere. As long as you carefully observe life, observe and think diligently when you encounter problems, and actively consult information, you can find the true meaning of science.

4. The biological chain in nature can be interpreted as a rope connected by metal links, while the food chain in nature refers to the interdependent chain relationship formed by animals, plants and microorganisms providing food to each other.
Biological chains are like necklaces, interlocking and indispensable. If people only rely on their own one-sided consciousness to destroy this relationship between creatures, it will bring serious ecological disasters.
For example, there is a story in America: once there was a lush grassland where people often went to graze, but some carnivores always stole their sheep, which made them very angry. They made a cruel decision to kill all the carnivores, and finally they wiped out all the sheep-eating animals nearby. They are very happy.
But they never imagined that because sheep had no natural enemies, they propagated very fast, and the grass on the grassland was obviously not enough for sheep to eat, which led to the sheep dying of hunger. Another example is 1958 sparrow hunting: in the 1950s, people listed sparrows as one of the four pests, and the whole country joined the ranks of sparrow hunting.
According to incomplete statistics, about 2 1 10,000 sparrows died in people's hands. When people are excited about killing these harmful birds, they don't know that sparrows are also guardians of nature.
A year later, a series of pests were found in garden plants, some of which were even devastating. People gradually realized the harm caused by destroying the biological chain and began to protect these sparrows, which they once regarded as bad birds.
In fact, no matter what animal it is, no matter how evil and cruel it is in your heart, it is the guardian of nature. We have to follow the endless biological chain of nature. For these animals, we should show more respect and don't let the story of deer and wolf happen again.
5. How to write a food chain fairy tale composition There are a group of happy birds in the city. They built a nest in the tree.
One day, all the birds went out to play. At this time, several workers' uncles brought saws and sawed off the tree.

The girl touched the bird's feather and said. The girl has a small cherry mouth, big eyes and dexterous hands. She is very beautiful.
The girl wanted to feed the birds at home, but when she thought about it, the birds were still free outside, so she built a nest for them under a banyan tree in front of the canteen opposite her home. The bird is very happy. It flies to tell its companions that they have a new home.
The companions flew happily to their new home together. Lovely birds go to the tree to sing every morning, noon and evening. My uncles and aunts who work in the canteen also like listening to birds singing.

So, my mother and I quarreled. But my mother doesn't eat hard or soft, and I can't help it. I have to use my killer weapon-crying. My mother, who loves me the most, really can't stand my tossing and turning, so she gives in easily.
Dad → me

On this day, I was watching TV, "Baby, come and help dad clean the floor!" " "Dad greeted me again." Don't! "I spit out two words bitterly." Let's go, or stop watching TV. "Dad came roaring. Looks like I'll just have to use a killer. "wow! "I tried to make myself cry more, but my father didn't buy it. He has no motivation for me to continue watching TV. Instead, he strode over and pulled me to the mop. ...
Mom → Dad
Although my father always bullies me, he is most afraid of my mother. On this day, my mother and I were watching TV, and my father came to watch TV. "No," said mother, "wash the dishes first." How dare my father talk back to my mother? I must wash the dishes.
Although my biological chain is not as wonderful as nature, it is also unique. Come and bask in your biological chain!
