There are poems about the material cycle.

1. "The endless grass on the plain comes and goes with each season; Wildfire never exhausted them, they grew taller in the spring breeze, and they were sweet on the old road. The resistance stability of Qing (1) ecosystem is related to the complexity of nutrient structure. The simpler the nutritional structure, the weaker the self-regulation ability and the weaker the resistance stability. (2) The eagle has the lowest energy, the lowest energy transfer efficiency and the longest food chain. Then the lowest energy value obtained by the eagle is 20000 *10% *10% *10% = 20kj. (3) When winter comes, the cold will stimulate the cold receptors in the fox skin, and the excitement generated by the receptors will be transmitted to the thermoregulatory center in the hypothalamus. Under the regulation of this center, keep the fox's body temperature stable. If the fox's heat production rate and heat dissipation rate are a 1 and b 1 respectively at room temperature, and a2 and b2 respectively in winter, a 1=b 1 and a2=b2 due to normal and constant body temperature, and a 1 due to more heat dissipation in winter.

2. List two ancient poems with biological knowledge. In April, flowers bloom in the world and peach blossoms bloom in mountain temples. It's about the relationship between biology and altitude.

Silkworms in spring will weave until they die, and candles will drain the wick every night. Abnormal development of insects.

In the autumn night, candlelight reflected the screen, and Fan slapped the fireflies with his hand. Fireflies glow.

But this spring spring, after all, can't be caged. Look, there is a pink apricot sticking out of the wall. Biological phototaxis.

The waterside pavilion gets the moon first. Flowers and plants facing the sun grow better. The relationship between biological growth and temperature.

I quit my job and go home, just like a flower falling from a branch, but this is not a heartless thing. It can be turned into the soil of spring and can also play a role in nurturing the next generation. The circulation of matter.

You don't have to go home when you meet, and Huang Die will be sad tomorrow. The photoperiod of plants.

If you plant flowers with your heart, you won't send them, but you have no intention of planting willows. Plant reproduction.

Crazy catkins dance with the wind, and fine peach blossoms chase water. The spread of seeds.

I planted beans at the foot of Nanshan, and the weeds in the field were covered with peas. Interspecific competition of organisms.

Poetry is a wonderful flower in the garden of ancient literature in China. With its gorgeous colors, charming charm and intoxicating fragrance, it has always attracted the attention of Chinese people. Do you know that?/You know what? There are many sentences describing biological phenomena in poetry. Our group found these by collecting and sorting them out. Let me show them to you. "Jasper makeup is as high as a tree, and thousands of green silk tapestries hang down." This is a description of willow species. After hearing such a poem, can campus and urban greening not choose willow trees? "Stop and sit in the maple forest late, and the frost leaves are red in February." This is a description of autumn leaves. As we all know, the color of leaves mainly depends on chlorophyll, but there are not only chlorophyll but also some other pigments in leaves. Take the maple leaf as an example. In autumn, chlorophyll decomposes and anthocyanins appear in the leaves, so the leaves turn red. The students all know Bai Juyi's poem "Recalling Jiangnan". "The river is as red as fire at sunrise and as green as blue in spring." How beautiful. But do you know how these beautiful colors are formed? For me, the first half sentence is easy to understand, and the second half sentence is our biological phenomenon, which is caused by the proliferation of algae. In a word, through our investigation, many poems are about biological phenomena.

The poem "April flowers are all over the world, and the peach blossoms in the mountain temple begin to bloom" describes such a scene. The peach blossoms at the foot of the mountain have all withered, but the peach blossoms on the mountain have just begun to bloom. It shows that flowering is affected by temperature conditions. In fact, there are poems describing this biological phenomenon. For example, "the sword front comes from sharpening, and the plum blossom fragrance comes from bitter cold", "The grass in your north is blue as jade, and the spring breeze blows high". We also found the poem "Falling red is not a heartless thing, but turning it into spring mud can protect flowers", which means that fallen leaves dissolve into the soil, are decomposed into inorganic substances by bacteria in the soil, and are reabsorbed by plants to provide nutrition for plants. The biggest feeling of our group is that there are many biological phenomena around us. As long as we observe them carefully, we will find the beauty of biology.

Goose, Goose, Goose, by A Xiang Tian Ge. White hair floating green water, red palm clear waves. "Did you see the beautiful scenery of white geese swimming in the water? This is a poem written by Luo when he was six years old. Everyone knows that, so you know what? It actually belongs to a kind of bird, and the wild goose is its ancestor. Everyone is familiar with Li Bai's Xiajiangling, right? "The apes on both sides of the strait can't stop crying, and the canoe has passed Chung Shan Man." Then who knows why apes keep barking? It's actually quite simple. This is a signal that they seek a mate, and it is also the language of animals. In fact, there are poems describing animal behavior, such as Jiang Xue by Liu Zongyuan and There are no birds in a hundred mountains, and there are no footprints in a thousand paths. Our group prefers the old fishermen here. His spirit of not being afraid of cold is really worth learning.

Meng Haoran's "Spring Dawn" "This spring morning, I woke up briskly and birds were singing everywhere. But now I remember that night, that storm, and I want to know how many flowers were broken. " The poet skillfully connects people-birds-wind and rain-flowers, so it is not difficult for us to imagine such an ecological environment: lush trees, birds and flowers, and pleasant climate. Let us realize the beauty of harmony and unity between biology and environment. In fact, there are too many such poems. "The hedge is thin and deep all the way, and the flowers on the tree head are not overcast. The children are scrambling to catch up with Huang Die, and cauliflower is nowhere to be found. " Draw an outline of an idyllic landscape for us. But now such a scene is hard for us to see and hear. Because our ecological environment is being destroyed day by day. What a cruel thing it is. So here we propose that we work together to make our environment better and more beautiful.
