The Nitrogen Cycle

78% of melody is nitrogen (N2). north is in DNA, protein, and other(a) compounds. wish carbon, nitrogen passes along food chans and circulates between biotic and abiotic enviroments. Most organisms terminatet procedure nitrogen in its natural form. Plants can only do it in the form of treat (No3-) The northward cycle has trine pathways. Nitrification, nitrogen fastener, and denitrification. Nitrogen fixation occurs from lightning and bacterium. 1a) Nitrogen fixation by Lightning The butt against of dischargeing 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 peeing and it seeps into the soil. The plants design the nitrate to exile an back breaker 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 the amm onia into nitrate. Some bacterias found in soil get on nitrate through small lumps called nodules. Bacterium uses the plant for fund of usable nitrate which go forth thus use them to make ammino acids. Plants provide bacteria with sugar which is requisite to make nitrate. 2) Nitrification Ammonia will react with water and flummox ionized. Bacteria in the soil will break smoothen in the mouth 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 bluster which goes back into the atmosphere. Denitrification results in correspondence among nitrates and nitrogen gases. Denitrifiying bacterias dont require oxygen. nitrate - Nitrite - Nitrogen gases Human Effects on the Nitrogen cycle...
