1, "Spring can't close the garden, but an apricot is out of the wall" (Song? Ye Shaoweng's "Not Worth Visiting the Garden" is the result of the phototaxis movement of plants, which can make the stems and leaves use light energy for photosynthesis in the most suitable position.
2. "The bright moon surprises magpie, and the breeze crows in the middle of the night" (Song? Xin Qiji's Xijiang Moon? Walking in the middle of the yellow sand at night) "Quejing" and "Zen Ming" This is an animal's response to external stimuli and belongs to biological stress.
Second, the matter in the biosphere is circular.
1, "falling red is not a heartless thing, but turning into spring mud protects flowers more" (Qing? Gong Zizhen's Ji Hai Miscellaneous Poems)
In the ecosystem, elements such as C, H, O, N, P, which make up living things, are constantly circulating. After the fallen flowers are decomposed by microorganisms, some mineral elements return to the inorganic environment and can be absorbed and reused by plants.
2. "Didn't you see how the water of the Yellow River moved out of heaven and into the ocean, never to return" (Tang? Li Bai's poem Into the Wine vividly describes the water cycle in the biosphere. Water from the surface, rivers and oceans will reach the land in the form of water vapor and finally return to the ground in the form of rain and snow. In this sense, it is reasonable to say "how can the water of the Yellow River move out of the sky".
Third, biology and environment are mutual.
1, "The moon comes first near the water tower, and flowers and trees spring early in the sun" (Song? Su Lin's poem to Fan Zhongyan)
In the process of growth and development, plants must absorb a certain amount of heat from the environment in order to complete a certain development stage. Because sunny flowers and trees receive sunlight for a long time and gain a certain amount of heat for a short time, they will develop faster.
2. "The world is full of flowers in April, and the peach blossoms in the mountain temple" (Tang? Bai Juyi's Peach Blossom in Dalin Temple) The external factors that affect the flowering of plants are mainly light and temperature. Because of the terrain, the temperature in mountainous areas is generally lower than that in the plains, so peach blossoms in mountainous areas bloom later than in the plains.
3. "Peach blossoms outside the bamboo are three or two, and the spring river is a duck prophet" (Song? Su Shi, a duck prophet, wrote that the duck's feeling of water temperature is completely related to the duck's splashing posture on the water surface, but it also reflects the influence of temperature, a non-biological factor, on the duck's living habits.
