Draw and describe biogeochemical cycle which can fix atmospheric N2
Answers
Nitrogen fixation. Atmospheric nitrogen occurs primarily in an inert form (N2) that few organisms can use; therefore it must be converted to an organic – or fixed – form in a process called nitrogen fixation. ...
Nitrification. ...
Assimilation. ...
Ammonification. ...
Denitrification.
Legume family
They contain symbiotic rhizobia bacteria within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants; this helps to fertilize the soil.Nitrogen gas from the atmosphere is fixed into organic nitrogen by nitrogen-fixing bacteria. ... Ammonium is converted to nitrit—NO2 minus—then to nitrate—NO3 minus—by nitrifying bacteria. Denitrifying bacteria convert the nitrate back into nitrogen gas, which reenters the atmosphere.The first step in the synthesis of virtually all nitrogenous compounds. Nitrogen gas is fixed into forms other organisms can use. The decomposers, certain soil bacteria and fungi, break down proteins in dead organisms and animal wastes, releasing ammonium ions which can be converted to other nitrogen compounds
Explanation:
atmospheric nitrogen can be fixed by three ways....Biologically,industrially and Electrically.
