The Nitrogen Cycle: Processes, Impact & Needs

Abstract Global nitrogen fixation contributes 413 Tg of reactive nitrogen to terrestrial and marine ecosystems annually of which anthropogenic activities

Every living thing needs nitrogen This activity will teach students about how living things are able to get the nitrogen they need to survive

product life cycle Free-living nitrogen-fixing bacteria are abundant in the soil and convert gaseous nitrogen into ammonium by reducing it This reduction is endothermic,

carbon cycle Nitrogen is taken up by plant roots and combined into organic substances in the plant, such as enzymes, proteins and chlorophyll Chlorophyll
