Transcript of "Energy flow"

  1. 2. <ul><li>Energy exists in many kinds of molecules </li></ul><ul><li>It cannot be created or destroyed </li></ul><ul><li>It simply transforms from one kind or energy to another through a variety of processes </li></ul><ul><li>We’ll start with how energy flows through living organisms by food </li></ul>
  2. 3. <ul><li>Autotrophs – (producers) – capture energy from the sun or the environment and convert it into &quot;food” </li></ul><ul><li>Heterotrophs – (consumers) – must get their energy from other living things </li></ul><ul><ul><li>Herbivores: eat plants </li></ul></ul><ul><ul><li>Carnivores: eat animals </li></ul></ul><ul><ul><li>Omnivores: eat plants and/or animals </li></ul></ul><ul><ul><li>Detritivores/decomposers: eat dead plant or animal material </li></ul></ul>
  3. 4. Utilized by the autotrophs!
  4. 5. <ul><li>the flow of energy can be shown through </li></ul><ul><ul><li>food chain </li></ul></ul><ul><ul><ul><li>a single line of predators and their prey </li></ul></ul></ul><ul><ul><li>food web </li></ul></ul><ul><ul><ul><li>shows more complex interactions understanding that organisms don’t eat just one type of food </li></ul></ul></ul><ul><ul><li>food pyramid </li></ul></ul><ul><ul><ul><li>shows, in measurable quantities, how much energy is required to feed the next level </li></ul></ul></ul>
  5. 6. <ul><li>Each step in a chain or web is called a TROPHIC LEVEL </li></ul><ul><li>Study the difference between primary, secondary and tertiary consumers </li></ul>
  6. 7. <ul><li>Autotrophs (producers) </li></ul><ul><li>Heterotrophs (consumers) </li></ul><ul><li>Herbivores </li></ul><ul><li>Carnivores </li></ul><ul><li>Omnivores </li></ul>
  7. 8. Some bacteria live in deep ocean vents, and make their food from chemicals in those vents
  8. 9. <ul><li>Autotrophs (producers) </li></ul><ul><li>Primary Consumers </li></ul><ul><li>Secondary Consumers </li></ul><ul><li>Tertiary Consumers </li></ul>
  9. 10. Confused? Try this link…it explains it all!
  10. 11. <ul><li>Matter (solids, liquids, gasses) doesn’t stop existing when it gets to the top of the pyramid </li></ul><ul><li>It gets naturally recycled through a series of cycles </li></ul><ul><ul><li>the molecules present in each part of the ecosystem do not get used up; they transform into other things </li></ul></ul><ul><ul><li>Water, carbon, oxygen, and nitrogen </li></ul></ul><ul><ul><li>Study the following cycles </li></ul></ul>
  11. 12. Click here for a description of the water cycle <ul><li>The basics </li></ul><ul><li>water falls as precipitation </li></ul><ul><li>soaks into ground; used by living organisms </li></ul><ul><li>evaporates or transpirates back into atmosphere </li></ul><ul><li>condenses back into liquid and falls again </li></ul>
  12. 13. Click here for a description of the carbon cycle. <ul><li>The basics </li></ul><ul><li>carbon from atmosphere gets transformed into food molecules through photosynthesis </li></ul><ul><li>living things eat food molecules </li></ul><ul><li>living things die and decompose </li></ul><ul><li>decomposed material turns into fossil fuels </li></ul><ul><li>burning fossil fuels or respiration returns carbon back to atmosphere </li></ul>
  13. 14. Link to description of the nitrogen cycle. <ul><li>The basics </li></ul><ul><li>exists as a gas in the atmosphere </li></ul><ul><li>must use bacteria to turn into solid form useable by plants </li></ul><ul><li>animals eat plants </li></ul><ul><li>plants and animals die returning nitrogen to the soil </li></ul><ul><li>more bacteria turn nitrogen back into gas form in atmosphere </li></ul>
  14. 15. Link to the description of the oxygen cycle. <ul><li>The basics </li></ul><ul><li>oxygen is produced through photosynthesis and released to atmosphere </li></ul><ul><li>oxygen is used during respiration and decomposition of dead organic matter </li></ul>
