Biogeochemical Cycles: the Nitrogen Cycle

Biosphere - Nitrogen Cycle, Microorganisms, Atmosphere nitrogen cycle Nitrogen fixation generally refers to the process in which atmospheric nitrogen is converted into ammonia Conversion of atmospheric N to ammonia calvin cycle The global nitrogen cycle is central to the biogeochemistry of the Earth, with large natural flows of nitrogen from the atmosphere into

product life cycle Step 1- Nitrogen Fixation- Special bacteria convert the nitrogen gas to ammonia which the plants can use ▫ Step 2- Nitrification- Nitrification
