生物脱氮的来源主要是植物和微生物。植物通过光合作用将二氧化碳和水转化为有机化合物,同时产生氧气。微生物则通过代谢将有机物分解为氮化合物。
一些英文例句包括:
"Nitrogen fixation is the process by which nitrogen gas is converted into a form that can be used by plants and other organisms." (脱氮是指将氮气转化为植物和其他生物可以使用的形式的过程。)
"Biological nitrogen fixation occurs in soil, water, and the atmosphere, and is essential for the nitrogen cycle in ecosystems." (生物脱氮发生在土壤、水和大气中,对生态系统中的氮循环至关重要。)
"Nitrogen-fixing bacteria are found in the roots of legumes, such as beans and peas, and help to enrich the soil with nitrogen." (脱氮细菌发现于豆科植物,如豆和豌豆的根部,有助于使土壤富含氮。)
