The Nitrogen Cycle Earth Science

nitrogen cycle  In general, the N cycle processes of fixation, mineralization and nitrification increase plant available N Denitrification, volatilization, immobilization, and Nitrogen is taken up by plant roots and combined into organic substances in the plant, such as enzymes, proteins and chlorophyll Chlorophyll

When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen Various fungi and prokaryotes A CONTINUAL PROCESS · Biological nitrogen fixation is the first step in the nitrogen cycle, occurring when atmospheric nitrogen is 'fixed' or converted into

1 The nitrogen cycle can increase the rate of primary production Nitrogen is considered one of the limiting factors in primary production Atmospheric 1 Nitrogen-fixing microbes like bacteria and blue-green algae convert nitrogen into inorganic nitrogen compounds This is called nitrogen
