Answer 1

Answer:



This figure summaries the global cycling of reactive nitrogen.[1] includes industrial fertilizer production,[2]nitrogen fixed by natural ecosystems,[3]nitrogen fixed by oceans,[4] nitrogen fixed by agricultural crops,[5] NOx emitted by biomass burning,[6] NOx emitted from soil,[7] nitrogen fixed by lightning,[8] NH3 emitted by terrestrial ecosystems,[9] deposition of nitrogen to terrestrial surfaces and oceans,[10][11] NH3 emitted from oceans,[12][13][11] ocean NO2 emissions from the atmosphere,[14] denitrification in oceans,[4][15][11] and reactive nitrogen burial in oceans.[5]



Schematic representation of the flow of nitrogen through the ecosystem. The importance of bacteria in the cycle is immediately recognized as being a key element in the cycle, providing different forms of nitrogen compounds assimilable by higher organisms .
