  1. IV. Ecosystem Ecology A. Energy Flow 1. Food chains 2. Productiion a. gross primary productivity b. net primary productivity 3. Consumption a. ecological efficiency 4. Decomposition 5. Trophic pyramids 6. What determines productivity

  2. Rocky intertidal community

  3. Simplified food web of a rocky intertidal community Pisaster (sea star) Thais (snail) Chitons 2 sp Limpets 2 sp Bivalves (Mussels) Acorn Barnacles 3 sp Goosenecked Barnacles 1 sp

  4. Disturbance

  7. Primary producer = plants (and other photosynthetic organisms)

  8. Primary consumer = herbivore (things that eat producers)

  9. Tertiary consumer = carnivore (animals that eat secondary consumers)

  10. Omnivore = animal that eats from several trophic levels

  11. Fig. 54.1

  12. Detritovore = organisms that eat non-living organic matter

  13. Respiration 6CO2 + 6H2O + Energy C6H12O6 + 6O2 Photosynthesis NPP = GPP - Respiration
