What ancient poems and sentences illustrate the influence of biological factors on biology?
Poems such as "Grassing across the plain, coming and going with the four seasons" and "Endless, the river and the moon are similar every year" contain the phenomenon of "growth and reproduction" of creatures.
"Wildfire has never exhausted them, and they are tall again in the spring breeze" can explain the stability of ecosystem resilience.

"The silkworm will weave until it dies, and the candle will weep every night" actually refers to the abnormal development of silkworm. The so-called silkworm death here actually goes through the stage of "larva → pupa".
"The children ran after Huang Die and flew into the cauliflower without finding it", which shows that Huang Die's body color and environment are very similar. This phenomenon is called "protective color" in biology and is the result of long-term natural selection.
A little red among evergreen trees not only shows the "warning color" in biology, but also shows the problem of "gene mutation" in biology.
"Falling red is not a heartless thing, but turning into spring mud protects flowers more", which thoroughly explains the characteristics of "material cycle of ecosystem": repeated appearance and cycle.
"In the fragrance of rice flowers, it is said that the harvest year is good, and frogs are heard one by one", which explains the relationship between frog protection and crop harvest. Protecting frogs is protecting natural enemies of pests.
The reason why February leaves are red is that chlorophyll synthesis in cells decreases and anthocyanin content increases due to the influence of temperature.
"Boil beans and burn beans, and beans cry in the pot; This is the same root, why rush to speculate with each other? " This vividly illustrates the problem of intraspecific struggle in biological struggle for existence.
"all loves can't be caged, and an apricot comes out of the wall", "Because of the wind, there is no catkin, only sunflower depends on the sun", which shows the phototropism of plants.
"As you sow, you reap" explains this genetic phenomenon. "One mother gives birth to nine children, even ten mothers are different" explains the variation phenomenon.
"The mantis catches cicada, and the yellowbird is behind" and "The big fish eat small fish, the small fish eat shrimp, and the shrimp eat mud" all explain the food chain relationship of the ecosystem, and can also explain the "predation" relationship among the organisms in the food chain.
From "unruly people enter barren land" to "green mountains and green waters are always in spring", it shows that the main factor affecting the ecosystem is forest.
"Fighting between snipes and mussels" vividly illustrates one of the ways of nerve regulation, "conditioned reflex".
"One mountain can't accommodate two tigers" is interpreted from the ecological point of view as "tigers are in the highest trophic level and get less energy, so the number of individuals should be less".
"I have no intention of planting flowers, and I have no intention of planting willows." Plants such as willow can reproduce their offspring by cutting and other asexual reproduction methods, while most plants reproduce their offspring by seeds, which belongs to egg reproduction in sexual reproduction.
"Born in Huainan is orange, born in Huaibei is orange. The leaves are similar to the disciples, but the taste is different. " 1, indicating that temperature affects the physiology of plants; (2) Changes in environmental conditions will cause biological variation; (3) With the increase of latitude, the temperature will gradually decrease, thus affecting the life activities of plants.
Wait until the double ninth festival, then come to chrysanthemum. Chrysanthemum is a short-day plant, which blooms in autumn and is affected by short-day in autumn.
"Shannan grows beans and the grass is full of bean seedlings." Field crops and weeds generally belong to interspecific competition. Only by clearing weeds in the field in time can the energy of farmland ecosystem flow to crops.
"Although the shin is short, the continuation is worrying; Although the crane handle is long, it is sad to break. " Duck leg bone: calf. All kinds of creatures can adapt to the environment, but different creatures adapt to the environment in different ways, which is the result of long-term natural selection.
"two orioles sing green willows, and a row of egrets go up to the sky." This is a famous sentence praising nature, which embodies the aesthetic value and beautiful artistic conception in the diversity of biological values. It not only makes students feel the beauty of nature, but also increases their awareness of protecting the environment and preventing environmental pollution.
"The sky is grey and wild, and the wind blows grass and sees cattle and sheep." This is a vivid description of grassland ecosystem in ecological balance. Grassland is an important base for animal husbandry production. Only by protecting the grassland and maintaining its ecological balance can human beings realize the sustainable development of animal husbandry production.
Do what you want and let the wind blow. "Doing the right thing" means planting crops at a reasonable density and making them stand upright. From the analysis of the influencing factors of photosynthesis, this method can expand the area and improve the intensity of light received by plants. Ventilation can increase the concentration of CO2 in the air around plants, which is beneficial to improve the efficiency of photosynthesis.
"Savages have no calendar days, and birds crow at four o'clock. Listen to the rules in February, and spring ploughing is not too late. Smell orioles in March, young hungry silkworms. April calls cuckoo and silkworm cluster. Uncle crow in May, young seedlings worry about grass. " Swallows come to Xindu, and pears come after Qingming. Light is a factor that affects the growth, flowering and reproduction of animals and plants. The migration of birds and the flowering of plants all have light time. Through long-term production and life practice, the working people have summed up the corresponding relationship between seasons, the growth and life of animals and plants and seasonal solar terms.
"You don't have to go home when you meet, and Huang Die will be sad tomorrow." (Su Songshi's "Wang Gong Jiu Tian Er Yun") The flowering of plants has obvious seasonality and belongs to the photoperiod of plants.

"Xiao dye frost drunk Lin who is it? Always in tears. " (Master Wang Yuan's "The West Chamber") The author used the blush after drinking to describe the maple leaves. Because there is a natural lack of an enzyme in the human body, it can't decompose acetaldehyde produced after alcohol enters the human body, so it blushes. Anthocyanins are acidic and industrial red, and the temperature difference between day and night in autumn is large, which decomposes chlorophyll and increases the relative amount of carotenoids. Anthocyanin becomes the main pigment, while maple cell sap is acidic at this time.
