5 Nitrogen (N) The nitrogen cycle is complex in part because of the many chemical forms of N: Organic-N; NO3; NH4; gases N2, N2O, NO + NO2 (=NOx). The nitrogen cycle is complex in part because of the many chemical forms of N: Organic-N; NO3; NH4; gases N2, N2O, NO + NO2 (=NOx). (NO), Nitric oxide (NO), Nitric oxide (NO2), Nitrogen dioxide (NO2), Nitrogen dioxide (N2O), Nitrous oxide (N2O), Nitrous oxide (N2) diatomic oxygen (N2) diatomic oxygen (NO2) nitrite (NO2) nitrite (NO3) nitrate (NO3) nitrate (NH4) ammonia, (NH3-) ammonium (NH4) ammonia, (NH3-) ammonium Accounting - distribution of N in grams times Accounting - distribution of N in grams times –Rocks and sediments 190,400,120(deep, unavailable) –Atmosphere 3,900,000 –Ocean 23,348 –Soils 460 –Land plants 14 –land animals 0.2

7 Nitrogen Pathways and Reactions: N2 to organic-N; called "N-fixation" (plants and humans) N2 to organic-N; called "N-fixation" (plants and humans) Organic-N to NH4+ ;"mineralization" (by bacteria and fungi) Organic-N to NH4+ ;"mineralization" (by bacteria and fungi) NH4+ to NO3-, producing NO2 and N2O; "nitrification" (by bacteria) NH4+ to NO3-, producing NO2 and N2O; "nitrification" (by bacteria) NO3- to N2, producing N2O ; "denitrification" (by bacteria) NO3- to N2, producing N2O ; "denitrification" (by bacteria) NO3- & NH4+ to organic-N; "photosynthesis" (uptake by plants) NO3- & NH4+ to organic-N; "photosynthesis" (uptake by plants)

15 III. Animals and plants A. How many? A. How many? B. What kinds? - Fish, crabs, shrimp, barnacles, oysters, sea shells, anemones, gorgonians, starfish, urchins, worms, sand dollars, algae (sea weeds). Avoid: sea cucumbers, sponges, and large fish. B. What kinds? - Fish, crabs, shrimp, barnacles, oysters, sea shells, anemones, gorgonians, starfish, urchins, worms, sand dollars, algae (sea weeds). Avoid: sea cucumbers, sponges, and large fish.

16 IV. Maintenance A. Evaporation and water changes A. Evaporation and water changes B. Cleaning B. Cleaning C. Feeding C. Feeding D. Problems and tips D. Problems and tips –1. Cloudy water and mortalities –2. Diseases and copper –3. Water color

17 VI. Collecting your own specimens A. Collecting A. Collecting –Temperature, aeration, biomass/vol. B. Handling and transporting B. Handling and transporting –Containers – dark and insulated

18 VII. Maintaining and feeding Community tank Community tank –No questionable additions –Do not feed for three days –Feed M,W, F only –No uneaten food, dead or decaying matter in tank at all –Return all unhealthy to nature OR have intensive care tank
