      Anmerkungen:

      • • Does not cycle through the atmosphere • Obtained from terrestrial rock  formations • Limiting factor on land and in freshwater ecosystems • Biologically important for producers and consumers
      1. NOT in atmosphere
      2. Limiting Factor - nutrient
   4. Nitrogen-FAND
      1. (de)nitrification
         1. N2 -> NH4+

            Anmerkungen:

            • nitrification
         2. NO3- -> N2

            Anmerkungen:

            • denitrification
      2. Ammonification
         1. NH4+ -> NO3-
      3. Nitrogen fixation
         1. org N -> NH4 +
7. Energy
   1. Trophic level - PCDD

      Anmerkungen:

      • As energy flows through ecosystems in food  chains and webs, the amount of chemical energy available to organisms at each  succeeding feeding level decreases.
      1. Food Chain & Food Web

         Anmerkungen:

         • • Food chain –Sequence of organisms, each of  which serves as a source of food for  the next • Food web –Network of interconnected food chains –More complex than a food chain
         1. Cycling of matter
         2. E flow
      2. Producer

         Anmerkungen:

         • (autotrophs) – Photosynthesis
      3. Consumer

         Anmerkungen:

         • (heterotrophs)  – Primary - herbivores – Secondary - carnivores – Third-level - omnivores
      4. Decomposer

         Anmerkungen:

         • Release nutrients from the dead bodies of plants and animals
      5. Detritive

         Anmerkungen:

         • Feed on the waste or dead bodies of organisms
      6. Production and Consumption of Energy

         Anmerkungen:

         • • Photosynthesis • Carbon dioxide + water + solar energy --> glucose + oxygen • Aerobic respiration • Glucose + oxygen --> carbon dioxide + water + energy
      7. Biomass
      8. Ecological efficiency - (-10%)
      9. Pyramid of energy flow
8. Technical term

   Anmerkungen:

   • Troph = feed , grow , nutrient Herb = grass carn = flesh omni = all auto = direct from within heter = difffrence vore = swallow percolation = refers to the movement and filtering of fluids through porous materials. guano = excrete from birds dolomite = translucent mineral
