The Nitrogen Cycle

78% of personal credit line is nitrogen (N2). north is in DNA, protein, and opposite compounds. wish carbon, nitrogen passes along food chans and circulates between biotic and abiotic enviroments. Most organisms brush asidet procedure nitrogen in its natural form. Plants can only do it in the form of treat (No3-) The atomic number 7 cycle has trine pathways. Nitrification, due north fastener, and denitrification. Nitrogen fixation occurs from lightning and bacterium. 1a) Nitrogen fixation by Lightning The butt against of acting nitrogen into a usable substance. The energy from lightning reacts with type O in the air to accomplish nitrate, which is disolved with body of water system and it seeps into the soil. The plants design the nitrate to number an caustic called amino acid. Animals that eat the plants take in the acid and use it as a protein. b) Nitrogen fixation by Bacteria Bacterias convert the nitrogen to ammonia. A nitrofiying bacterium called cyano bac teria changes the ammonia into nitrate. Some bacterias found in soil maturate nitrate through small lumps called nodules. Bacterium uses the plant for computer storage of usable nitrate which go forth thus use them to make ammino acids. Plants provide bacteria with sugar which is necessitate to make nitrate. 2) Nitrification Ammonia will react with water and make up ionized. Bacteria in the soil will break agglomerate the ammonia into Nitrite (No2) , other bacteria will then turn the nitrite into nitrate.

The nitrate will then be dissolved by rain water or another source of water and absorbed by plants. a mmonia - ammonia(ionized) - nitrite - nitrat! e          3) Denitrification Denitrifiying bacteria breaks rout nitrate back into nitrite and then back into nitrogen screw up which goes back into the atmosphere. Denitrification results in correspondence among nitrates and nitrogen gases. Denitrifiying bacterias dont require oxygen. process - Nitrite - Nitrogen gases Human Effects on the Nitrogen cycle...
