Food chain composition

In daily study, work and life, everyone will inevitably come into contact with composition, which can be divided into narrative, explanatory, practical and argumentative according to different genres. Still at a loss for composition? The following are four food chain components I collected for your reference, hoping to help friends in need.

Food chain composition 1 Everyone knows that there is a "food chain" between animals. Now I find that my family also has an interesting "chain".

That was last winter. One day, I got sick and took my temperature. Wow, I screamed with fear, 38 degrees 5. Dad, who is studying, heard the sound and ran over at once. I clamored for my father to accompany me to see a doctor. Dad frowned and said slowly, "It's just a little hot. What's the fuss? Just take some medicine instead of going to the hospital. " If you are obedient, I will take you to the park for a day tomorrow. "

When my mother came back, I was at my wit's end. When she heard this, she jumped up and said to her father, "It doesn't matter if it's a little hot. If a minor illness is not cured, it will become a serious illness! " How to burn your body? You don't feel bad, I still feel bad! I am such a precious daughter, and I don't want her to suffer! "With my mother's support, I shouted even harder.

Dad had no choice but to stop talking. I wanted to take the opportunity to peel it off, so I shouted, "Mom, I have no taste in my mouth. Please buy me some chewing gum, olives and watermelon juice. " Who knows, my mother also pulled up her face: "Good heart, are you going to see a doctor or buy something to eat?" "Hey, children don't buy anything if they want to eat!" Grandma heard this and cursed and walked out of the room.

"If you don't buy it, I will buy it." Say that finish, reached into his pocket to pay.

"Mom, don't be angry. Can't I buy a heart? " Mom keeps talking. Then my father came in and said, "Alas, my heart won with the help of my grandmother." The whole family laughed, and my illness seemed to be cured. Look, there is such a "chain" in our family: I am afraid of my father, my father is afraid of my mother, my mother is afraid of my grandmother, and my grandmother dotes on me. It's really weird.

Ah! This interesting "chain" makes my family harmonious and happy.

There are many food chains in nature, and my family also has a naturally formed "food chain". I'm afraid of my father, my father is afraid of my mother, my mother is afraid of my sister, and my sister is afraid of me.

My father is like a tiger in my eyes, and I see my father as a frightened rabbit. I really want to sleep in on Sunday. My mother told me to get up early to review my lessons, but I didn't listen and yelled at her. At this moment, my father came into my room, and I quickly covered my head with a quilt. I heard my dad yelling, "I'm a senior in high school and I'm still so lazy." What a scandal? " Say that finish, will drag me out of the quilt. Seeing him like this, I dare not resist, so I have to "surrender" obediently. Dad, this tiger is terrible!

Don't look at my dad in front of me, in front of my mother-well, don't joke about it. He looks like an old fool in front of my mother. My mother got up in the morning, he followed, and then took my mother to school by motorcycle. In the afternoon, I picked her up on time. One day, he couldn't pick up his mother because of something. At night, as soon as my mother walked into the house, her face was overcast. Seeing that the situation was wrong, my father rushed to my mother's side and said with a smile, "Please calm down. Please be angry if I have something to delay picking you up today. It won't happen again. " After hearing this, my mother's face "turned cloudy and sunny."

Who knows, my mother is not afraid of "tigers" but "little sheep", that is, my sister. My sister was born with a good voice. She cried and laughed earth-shattering. Once, her mother took her shopping. She saw a toy Q in the shop and forced her mother to buy it. Mom said it was something for boys to play with and didn't buy it for her. My sister had a brainwave, sitting on the ground, crying and shouting, yelling at her and looking at her mother through her fingers. My sister's behavior is really smart. Mother was afraid of jokes, so she quickly pulled her sister up and bought her a toy Q. At this moment, "Little Sheep" smiled with satisfaction.

Seeing this, you don't think my "king" is my sister. In fact, she also has people who are afraid. Who is this man? Miss Ben, of course! Yesterday, my sister bought a lot of sweets from the shop and planned to keep them all for herself. I didn't expect to find it, so I called my sister to my side and said, "What did you buy just now?" Show it to my sister. "My sister looked at me timidly and gave me five sweets." This guy is so stingy! "I thought like this, but I still pretended to be happy on my face and said to my sister," My sister will buy you a lot of delicious food next week, mutton kebabs, pineapples ... "My sister quickly gave me more than half of the candy without saying anything. Well, I think I'm confused by my sweet words. Oh, that's a clever move.

To tell the truth, who doesn't want to sit on the throne of the "old emperor"? Who wants to be this "slave" who is "oppressed"? To this end, we are all secretly competing. Dad is attacking "advanced workers", mother is attacking "excellent teachers" and little sister is attacking "three good students". This young lady is even more ambitious-attacking famous schools. We all work hard, encourage and learn from each other.

However, as far as I am concerned, the "food chain" of my family will not change after we reach the set goals.

We know that all living things need food. For example, a person, a fish, a bird or even a bug. Without food, all living things will die. In the world, different kinds of animals have different living habits. They live in a large community in the biosphere and are closely connected through the food chain.

In this food chain, some creatures are producers and some creatures are consumers. Plants are producers because they use sunlight, soil and other ingredients to produce food. Animals are consumers because they eat plants and other animals.

There are four different consumers in the animal kingdom. Carnivores only eat other animals, such as lions. Herbivores only eat plants, such as antelopes. Omnivores eat both animals and plants, such as us humans. Saprophytic animals feed on dead animals, such as vultures on the Qinghai-Tibet Plateau.

Let's make a chart: grasshoppers eat leaves, hungry voles eat grasshoppers, snakes eat voles and eagles eat snakes. In this way, these animals and plants are connected with each other through food.

The food chain in a region is in a state of dynamic balance. We call it ecological balance. We can't destroy it artificially. Otherwise, we will reap the consequences. For example, in 1930s, in order to control pests in sugarcane fields, Australia introduced a toad from the United States, but this animal was very toxic and had almost no natural enemies. Any animal that eats them will die. In just a few decades, their number has reached millions, and it is increasing by 20% every year. Wherever they went, some animals were wiped out. Now people must find a way to control this harmful animal.

The ecological balance between food chains in the biosphere is the result of natural selection and a natural law, which we must abide by. Otherwise, only we humans suffer.

There is a food chain in nature, and so does my family. Now, I will introduce my special food chain to you.

I'm afraid of dad. As soon as dad shouted, I obeyed; I noticed those words as soon as my father stared at me. Once, I got 88 points. When I got home, my father read the newspaper, and before I could speak, he cooked me a "belt-fried shredded pork" meal. Dad is like a tiger. I'm scared!

However, my father is a paper tiger in front of my mother. Once, my father left me at home, but I went out to eat and drink and came back very late. Scared me to cry and shout at home. Later, my mother found out about it and scolded my father. Dad was silent with his head down, as if he were at the mercy of his mother. Every time I see my father being quarreled by my mother, I am secretly happy: "Finally someone can control you!" " "

Where's mom? How strange! Mother is afraid of her sister. One Saturday, my mother took my sister and me to the shopping center. My sister took a fancy to a mechanical pencil and pestered my mother to buy it. Mom looked at the price, which was a little expensive. Mom didn't want to buy it, so she took her sister away. However, my sister said loudly, "No, I want it!" I won't go unless you buy it for me! "Mom listened, hesitated, or bought it. My sister smiled smugly.

My sister is still a little afraid of me. Once, I took a beautiful little fan. When my sister saw it, she immediately snatched the small fan from my hand. I said loudly, "Give it to me!" I was a little scared when I called my sister and said, "I won't give it to you!" " "I turned supercilious look and came up with an idea. I pretended to look at the picture book and said, "How interesting this book is! There are so many comic characters, it's really nice! " Said, and deliberately looked at my sister. Sister finally said, "Sister, will you show it to me?" "No, unless ┅ ┅" my sister interrupted me and said, "unless what? "I saw my sister cheating, so I said," Unless you return my fan! " "I raised my voice. "Good, good!" Sister said, and threw the small fan to me. Look, is my sister afraid of me?

There is a "food chain" in my family-I am afraid of my father, my father is afraid of my mother, my mother is afraid of my sister, and my sister is afraid of me. I like my food chain, and I love my family!
