  1. WARM UP 4/9 – write in notebook 1. What was tested for each experiment? 2. Which variable influences rate of dissolving the most?

  2. ENERGY FLOW

  3. Food Web

  4. Why are food webs important?

  5. Energy Flow Model

  6. With a partner discuss: • If the food chain had continued to the next level, what percentage of energy would the next level consumer have received from the previous consumer? • How much water would you have transferred into the the next level consumer’s cup? • Judging from this activity, why do you think most food chains never go higher than 2nd or 3rd level consumers?

  7. Fill in the blanks http://schoolworkhelper.net/wp-content/uploads/2011/01/EnergyPyramid-26a65z5.gif

  8. Fill in the Blanks C kcal Bkcal 250 kcal A kcal http://www.proprofs.com/quiz-school/upload/yuiupload/244802756.jpg

  9. It’s your turn… • Create an energy pyramid with the correct food chain and energy flow. • Remember – only 10% of the energy is absorbed from level to level! • Ex: Hawk (2nd carnivore) – 2 kcal Snake (1st carnivore) – 20 kcal Grasshoppers (omnivore) – 200 kcal Grass (producer) – 2000 kcal
