  • The efficiency of ecosystem
    • The Trophic level
    • Producers
      • Primary Consumers
        • Secondary consumers
          • Tertiary consumers
            • Decomposers
    • Pyramid of biomass
    • Secondary production
    • Gross primary productivity (GPP) - measured in g m-2 year-1
    • Net primary productivity (NPP)
      • NPP=       GPP - R

      • Ammonium compounds
        • Nitrifying bacteria
          • Nitrogen fixing bacteria
            • Converts nitrogen from soil air into ammonium

    • How is energy lost between trophic levels in ecosytems
      • In plants
        • 1-3% of light use for energy
        • 90% is reflection
        • Incorrect wavelength
        • Transmission of light right through
        • Used as heat power
        • In animals
          • Heat loss
          • Respiration
          • Faeces
