Biochemical Cycles

( \newcommand{\kernel}{\mathrm{null}\,}\)

  • Biochemical Cycles
  • Carbon Cycle
  • Nitrogen Cycle
    Nitrogen in the air becomes a part of biological matter mostly through the actions of bacteria and algae in a process known as nitrogen fixation. Legume plants such as clover, alfalfa, and soybeans form nodules on the roots where nitrogen fixing bacteria take nitrogen from the air and convert it into ammonia, NH3. The ammonia is further converted by other bacteria first into nitrite ions and then into nitrate ions.
