Questions 8-10 refer to Model 1. 8. If the amount of energy (measured in kilocalories (kcal)) contained in the Producer level Is 319,000 kcal, calculate the amount of energy in kcal contained in the other 3 levels. Write this on the blanks to the left of the pyramid. 9. The arrows in Model 1 represent the energy available to the next level of the pyramid. a. What percentage of energy is transferred from one energy level to the next? b. How much of the initial energy (what hit Earth's surface) is available to the blue jays?

________ ________ ________

Shade the fourth (top) level of each pyramid red

Shade the third level of each pyramid blue

Shade the second level of each pyramid yellow

Shade the first (bottom) level of each pyramid green

Directions: 1. Color the levels based on

the directions below. 2. Use your Yellowstone food

web to identify organisms that would be at each of the 4 levels on the pyramid. Write the names of the organism on the 4th side of the pyramid. 3. Cut along the outer shape of your pyramid and fold on the lines radiating from the center. 4. Write your name and period number on the back of the pyramid. 5. Fold the flap under and tape or glue it together.
