Energy Flow and Trophic Structure

Energy Capture. Heterotrophs: obtain energy from organic sources or from other organismsAutotrophs: obtain energy from inorganic sourcesPhotoautotrophs and chemoautotrophs. Energy Capture and Use. Photosynthesis and respirationPhotosynthesis: 6 CO2 6 H2O -> C6H12O6 6O2Respiration: C6H1

    1. Energy Flow and Trophic Structure Chapter 14

    2. Energy Capture Heterotrophs: obtain energy from organic sources or from other organisms Autotrophs: obtain energy from inorganic sources Photoautotrophs and chemoautotrophs

    3. Energy Capture and Use Photosynthesis and respiration Photosynthesis: 6 CO2 + 6 H2O -> C6H12O6 + 6O2 Respiration: C6H12O6 + 6O2 -> 6 CO2 + 6 H2O Primary production: energy capture via photosynthesis into organic molecules Biomass: amount of E stored in dry weight of organic matter

    4. Energy, Production and Biomass Standing crop biomass: fraction of total biomass in living plant tissue Gross primary production: total rate of energy accumulation Net primary production: gross primary production minus respiration
