Transcript

  • 1.  
  • 2. Meal Food Web
    • This activity is to see how we, as humans, still fit into our natural food web
    • Start by coming up with your fantasy daily meal plan (FDMP)
    • Your FDMP must include a breakfast, a lunch and a dinner. You may include one snack
  • 3. Instructions
    • Each meal must include an “Entrée”, at least 2 sides (may be more if you want), a drink (can use water for only one of the meals), desserts are optional, but separate than the 2 sides.
    • Write them down in your notes, doesn ’t have to be a new piece of paper
  • 4. The Table
    • On a clean sheet of paper, put your name & hour at the upper right
    • Put a title at the top “Meal Food Web”
    • Create a 5 column table
    • You need to have space for all of your food
  • 5. Your Table Might Look Like This Your Meals Parts of your Meals Ingredients Organisms that create those ingredients What those animals eat
  • 6. The Web
    • On the back of your table, list out all of the plants from the column “organisms that make those ingredients” and “what those animals eat”
    • Spread them out! Don ’t group them or list them
    • List out all of the animals that are in the column “organisms that make those ingredients” Be sure to include YOU… again, spread them out!
  • 7. The Web
    • Draw arrows to show “what eats what”
    • Add in arrows to show “potential” food sources for animals
      • Example: Your table may say that a cow eats hay, oats and corn, but in your web there is also grass…you should add an arrow from the grass to the cow
  • 8. The Contenders
    • You will now add in some competition in your food web
    • Think of 5 animals that will compete with YOU for your food
    • Your food is anything that is in your web right now.
    • Add those animals in, CIRCLE them then connect them in with arrows as many times as possible.
  • 9. Conclusion
    • What is the ultimate source of energy for your food web?
    • If all of the corn or any other one of your producers disappeared, how would that affect your web?
    • Separate your web into: Producers, 1 st level Consumers, 2 nd level Consumers, 3 rd level Consumers
  • 10. Conclusion (con ’ tinued)
    • What levels would be considered:
      • Herbivores
      • Omnivores
      • Carnivores
    • What is a detritivore? Put three in on your web, put a square around each of them and link them each with at least 3 things.
    • What level has the most organisms in it, in most food webs?
