slide1. Ecosystems Unit Activity 2.3 Evidence-Based Arguments for the Meadow Simulation 1<br>
slide2. Unit map You are here 2<br>
slide3. Complete the Evidence-Based Arguments Tool 3<br>
slide4. Comparing ideas with a partner Compare your evidence, conclusions, and unanswered questions for each of the Three Questions.
How are they alike?
How are they different?
Consider making revisions to your argument based on your conversation with your partner. 4<br>
slide5. Question 1: What happens over 100 years when each population starts with an organic matter mass of 500? 5<br>
slide6. Question 2: What settings lead to the highest fox organic matter after 100 years? 6<br>
slide7. Question 3: What settings lead to all the foxes dying? 7<br>
slide8. Conclusion #1: The Organic Matter Pyramid The organic matter diagram that shows the maximum fox and rabbit mass in the Meadow Simulation resembles a pyramid. 8<br>
slide9. Conclusion #2: When Foxes All Die Only three final organic matter diagrams are possible in the meadow ecosystem. Foxes are more likely to die out than rabbits or grass. 9<br>
slide10. Discussion Questions What are the processes that lead to the organic matter pyramid?
Why are foxes more likely to die out than rabbits or grass? 10<br>
slide11. Results of the Meadow Simulation Take out your completed 2.2 Meadow Simulation Worksheet
What was the maximum organic mass of foxes that you observed at the end of the 100-year simulation (any trial)?
What was the maximum organic mass of rabbits that you observed at the end of the 100-year simulation (any trial)?
What was the maximum organic mass of grasses that you observed at the end of the 100-year simulation (any trial)? 11<br>
slide12. Discussion Questions In any trials did foxes completely die out? How do we explain this?
If grasses, rabbits, and foxes all survived for 100 years, the final mass of each population at the end of the simulation was always about the same. How do we explain this? 12<br>
slide13. Meadow Simulation Class Results: What initial biomass settings lead to the highest fox biomass? 13<br>
slide14. How are pools and the biomass pyramid related? 14<br>
