The Changing Nitrogen Cycle

Four processes participate in the cycling of nitrogen through the biosphere: nitrogen fixation, decay, nitrification, and

Nitrogen fixation generally refers to the process in which atmospheric nitrogen is converted into ammonia Conversion of atmospheric N to ammonia

nitrogen cycle 1 Nitrogen-fixing microbes like bacteria and blue-green algae convert nitrogen into inorganic nitrogen compounds This is called nitrogen

cell cycle Primary producers need a lot of nitrogen to be able to convert sunlight into energy Chlorophyll is the part of a cell in these primary producers that conducts
