  1. Ecosystem Function Notes

  2. Producers(Autotrophs) • Photosynthesis CO2 + H2O + Light Energy = Sugars C6H12O6 + O2 Not very efficient

  3. Producers(Autotrophs) • Chemosynthesis • Can convert simple compounds into more complex nutrient compounds without light

  4. Chemosynthesis • Black Smokers • http://www.pmel.noaa.gov/vents/nemo/education/movies/black_smoker.html

  5. Consumers(Heterotrophs) • Herbivores • Primary Consumers • Plant Eaters • Grazers • Ex.

  6. Consumers(Heterotrophs) • Carnivores • Secondary Consumers • Meat Eaters • Ex. • Tertiary Consumers • Meat Eaters that eat the meat eaters • Ex.

  7. Consumers(Heterotrophs) • Omnivores • Eat both producers and consumers • Ex.

  8. Consumers(Heterotrophs) • Detritivores • Detritus Feeders • Scavengers

  9. Consumers(Heterotrophs) • Detritivores • Decomposers • Microorganisms that convert organic compounds to simpler compound that can be taken in by producers. • Bacteria • Fungi

  10. Trophic Levels • 1st Level Producers • 2nd Level Primary Consumers (herbivores) • 3rd Level Secondary Consumers (carnivores)

  11. Trophic Levels • How does the amount of energy available change as you go up Trophic Levels?

  12. Pyramid of Energy • 10% Rule

  13. Pyramid of Energy Available

  14. Energy Efficienct in Ocean

  15. Trophic Levels • How does the biomass change as you go up Trophic Levels?

  16. Pyramid of Biomass

  17. Trophic Levels • How does the number of organisms change as you go up Trophic Levels?

  18. Pyramid of Numbers

  19. Energy Flow in an Ecosystem

  20. Energy Flow in an Ecosystem

  21. Energy Efficiency

  22. Food Web

  23. A Marine Food Web
