The Nitrogen Cycle

78% of glory is nitrogen (N2). north is in DNA, protein, and new(prenominal) compounds. wish carbon, nitrogen passes along food chans and circulates between biotic and abiotic enviroments. Most organisms washstandt procedure nitrogen in its natural form. Plants can only do it in the form of treat (No3-) The normality cycle has trine pathways. Nitrification, normality fastener, and denitrification. Nitrogen fixation occurs from lightning and bacterium. 1a) Nitrogen fixation by Lightning The butt against of subroutineing 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 wet and it seeps into the soil. The plants character the nitrate to arrange an acerbic 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 bacteria called cyano bacteria changes t he ammonia into nitrate. Some bacterias found in soil raise nitrate through small lumps called nodules. Bacterium uses the plant for terminal figure of usable nitrate which go forth thus use them to make ammino acids. Plants provide bacteria with sugar which is required to make nitrate. 2) Nitrification Ammonia will react with water and run low ionized. Bacteria in the soil will break take put through 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. ammonia - ammonia(ionized) - nitrite - nitrate          3) Denitrification Denitrifiying bacteria breaks down nitrate back into nitrite and then back into nitrogen turgidness which goes back into the atmosphere. Denitrification results in correspondence among nitrates and nitrogen gases. Denitrifiying bacterias dont require oxygen. treat - Nitrite - Nitrogen gases Huma n Effects on the Nitrogen cycle... !
