Nitrogen cycle

Nitrogen cycle, circulation of nitrogen in various forms through nature Nitrogen, a component of proteins and nucleic acids, is essential to life on Earth

Free-living nitrogen-fixing bacteria are abundant in the soil and convert gaseous nitrogen into ammonium by reducing it This reduction is endothermic,

product life cycle Nitrogen fixation generally refers to the process in which atmospheric nitrogen is converted into ammonia Conversion of atmospheric N to ammonia

calvin cycle 1 The nitrogen cycle can increase the rate of primary production Nitrogen is considered one of the limiting factors in primary production Atmospheric
