2. Seats: period 5

3. Catalyst 4 minutes! • Put these organisms in order from lowest to highest energy level: carnivore, herbivore, producer • What is the difference between food chains & webs? • Why are all producers green? • What is the definition of a producer? • What type of consumer are humans? • What type of consumer are vegetarians? How does an herbivore, like a cow, depend on the energy of the sun for food? What happens when the sun dies?

6. unit 7: ecology

7. Objectives • Agenda • Catalyst 5 • Food Chains Flash Back! 5 • Food Web Intro 5 • Guided Practice 5 • Partner Practice 20 • Food Web Puzzle 10 • Exit Ticket 5 • We are learning to… • Analyze relationships in ecological systems • We will be successful when we can… • Use a food web to identify producers, consumers, & decomposers science genius!

8. Flash back | Producers and Consumers All organisms can be divided into 2 groups based on how they get their energy: • Producers • Produce or make their own food via photosynthesis • Consumers • Consumefood or get energy by eating other organisms

9. Food Chains A food chain shows the flow of energy from one organism to another Secondary Consumer Producer Primary Consumer

10. Food Chains Decomposersbreak down dead organismsto obtain energy How might the real world be more complicated? Decomposer

11. Food Webs A food web shows how all organismsin an ecosystemare connected.

12. Food Webs • Arrows show the direction that energy is moving • For example, the snake eats the mouse and the frog

13. Guided Practice LEVEL ONE 1. Which animals eat the plants? 2. Which animals are carnivores? Mouse, Cricket, Rabbit Snake, owl, frog

14. Guided Practice LEVEL TWO 3. What is the producer in this web? 4. What are the primary consumers in this web? Plant Rabbit, mouse, cricket

15. Guided Practice LEVEL TWO 5. What are the secondary consumers in this web? 6. What is the tertiary consumer in this web? Frog, snake, owl Owl, snake

16. Guided Practice LEVEL THREE 7. Imagine a virus wipes out most of the frog population. How would this impact the… • Owl population? • Rabbit population? Decrease (less food) Increase (fewer owls = fewer predators)

17. Round 1 Identify the producers

18. Round 1 Identify the primary consumers

19. Round 1 Identify the secondary consumers

20. Round 1 Identify the tertiary consumers

21. Round 1 Identify the quaternary consumers

22. Round 2 Identify the relationship between the sparrow and the grasshopper

23. Round 2 Determine what would happen to the garter snake population if the red-tailed hawk population decreased

24. Round 2 Determine what would happen to the hognose snake population if the toad population increased

25. Round 2 Determine what would happen to the sunflower population if the rabbit population decreased

26. Round 2 Determine what would happen to the rabbit population If the oats population were to go extinct

27. Round 3 Determine what would happen to the sunflower population if the sparrow population decreased. Explain!

28. Round 3 Determine what would happen to the spider population if the hognose snake population increased. Explain!

29. Round 4 What do the arrows represent in the food web above?

30. Round 4 Where does the energy go after it reaches the hawk?

31. Food web Puzzle • Use the clues in the puzzle to create a food web for this ecosystem • Once complete, use the food web you created to answer the questions below

32. Exit Ticket 4 minutes! 4 minutes! • You may use your assignments! • You must work quietly & independently. • Talking will NOT be tolerated. BIG goal = 80% 0

33. Turn it in  homework due YESTERDAY!
