Transcript

  • 1.  
  • 2. Food Chain A path of food consumption beginning with the sun. Example: Sun Grass Rabbit Hawk Bacteria
  • 3. Tropic Levels
    • Level of consumption in a food chain.
      • Autotrophs or Producers
      • Herbivores or Primary Consumers
      • Carnivores or Secondary Consumers
      • Decomposers
  • 4. Autotrophs
    • or Producers make their own food through photosynthesis. The sun is needed for photosynthesis.
    • This is the first trophic level.
    Which organism below would be an autotroph ? Sun Grass Rabbit Hawk Bacteria
  • 5. Herbivores
    • Primary Consumers eat the plants which
    • are the autotrophs.
    • This is the next trophic level.
    Which organism below would be an Herbivore ? Sun Grass Rabbit Hawk Bacteria
  • 6. Carnivores
    • Secondary Consumers eat the primary consumers. There can also be tertiary consumers that eat the secondary consumers.
    • This is the third trophic level.
    Which organism below would be an Secondary Consumer ? Sun Grass Rabbit Hawk Bacteria
  • 7. Decomposers
    • Decomposers break down the dead plants and animals.
    • This turns them back into soil which the plants need.
    • This is the last trophic level.
    Which organism below would be an Decomposer? Sun Grass Rabbit Hawk Bacteria
  • 8. Forest Food Chain Sun Grass Grasshopper Toad Snake Hawk Bacteria
  • 9. Food Webs
    • Most food chains are interconnected .
    • Anr-imals typically consume a varied diet and, in turn, serve as food for a variety of other creatures that prey on them.
    • These interconnections create food webs.
