English Dictionary

nitrogen cycle

名詞

The natural circulation of nitrogen, in which atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

日本語の意味

窒素循環: 自然界における窒素の循環過程で、大気中の窒素が落雷などの作用により窒素酸化物に変化し、雨によって土壌に運ばれ、植物に吸収され、動物に摂取されたり、分解されたりする過程

The nitrogen cycle, in which atmospheric nitrogen is converted by lightning into nitrogen oxides that are deposited in the soil by rain and then assimilated by plants or returned to the atmosphere by bacteria, is essential to ecosystem functioning.

窒素の循環は、大気中の窒素が雷によって窒素酸化物に変化して雨で土壌に沈着し、植物に取り込まれて動物に食べられ（糞として戻されることもある）か、あるいは細菌によって再び元素状の窒素に分解されるという過程を含み、生態系の機能に不可欠です。
