  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

  5. Fig. 53.19 Succession on glacial moraines

  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
