Energy flow

  1. 1. Energy FlowSunday, March 24, 13
  2. 2. Energy Transfer How energy (food, nutrients) move through an ecosystem • Food Chains • Food Webs • Energy PyramidsSunday, March 24, 13
  3. 3. Energy Pyramid Shows how energy moves through an ecosystem. Each level has less than the level below. called Trophic levels.Sunday, March 24, 13
  4. 4. Trophic LevelsSunday, March 24, 13
  5. 5. Trophic Levels Energy moves from one organisms to another when it is eatenSunday, March 24, 13
  6. 6. Trophic Levels Energy moves from one organisms to another when it is eaten Each step in this transfer of energy is know as a trophic levelSunday, March 24, 13
  7. 7. Trophic Levels Energy moves from one organisms to another when it is eaten Each step in this transfer of energy is know as a trophic level The main trophic levels are producers, consumers, and decomposersSunday, March 24, 13

  10. 10. ProducersSunday, March 24, 13
  11. 11. Producers• A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (sugar/food)Sunday, March 24, 13
  12. 12. Producers• A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (sugar/food)• Called Producers because they produce all of the food that consumers useSunday, March 24, 13
  13. 13. Producers• A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (sugar/food)• Called Producers because they produce all of the food that consumers use• Without producers, there would be no life on this planetSunday, March 24, 13
  14. 14. Producers• A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (sugar/food)• Called Producers because they produce all of the food that consumers use• Without producers, there would be no life on this planet• not all producers have leaves but all use photosynthesisSunday, March 24, 13
  15. 15. Producers• A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (sugar/food)• Called Producers because they produce all of the food that consumers use• Without producers, there would be no life on this planet• not all producers have leaves but all use photosynthesis • Plants and AlgaeSunday, March 24, 13

  22. 22. Consumer• Organisms that do not make their own foodSunday, March 24, 13
  23. 23. Consumer• Organisms that do not make their own food• Must eat to surviveSunday, March 24, 13
  24. 24. Consumer• Organisms that do not make their own food• Must eat to survive• Consumer because they consume other organisms in order to liveSunday, March 24, 13
