Evolution and Survival in Nature

1. Warm up # 28 ( Unit 2 Article Due Tomorrow) • What do you know about the following terms: • Evolution • Community • Extinction • Genes 2) Describe what you see in video on “Maple Copters”

2. Things in nature look the way they do for a reason. Organisms that have an advantage will survive. Other organisms will go extinct. In nature there are 2 keys to survival: gaining energy and reproducing.

3. Warm Up # 22 • What makes you unique? • What does the word “evolution” mean? • Why do you think species would change over time?

4. Warm Up 29 • You and a friend are chased by a grizzly bear. List some possible ways you can survive. (not harming the bear) • A school of fish are chased by a shark, which fish gets eaten?

5. 3) Which of the fish are most likely to reach adulthood and reproduce? 4) What does the word “evolution” mean?

6. Things in nature look the way they do for a reason. Organisms that have an advantage will survive. Other organisms will go extinct. In nature there are 2 keys to survival: gaining energy and reproducing.

7. Warm Up 30 (5 questions) 1) Explain how this diagram illustrates evolution?

8. 2) A reintroduced population of wolves in a national park is 90% grey and 10% black, consistent with the wolf population in other regions. After several generations in isolation, the national park’s wolf population is 60% grey and 40% black. The wolf population has likely experiencedA. natural selection.B. genetic drift.C. mutations.D. migration.

9. 3) How is the fish on the bottom an example of evolution by mutation?

10. 4) Explain resistance.

11. Things in nature look the way they do for a reason. Organisms that have an advantage will survive. Other organisms will go extinct. In nature there are 2 keys to survival: gaining energy and reproducing. Need to fit your habitat! 5) Explain how/why a desert fox might look different than one in Audubon.

12. Warm Up 31: Matching…8 questions • Humans breed dogs a) natural selection • Genetic characteristics of b) evolution population change c) artificial selection 3) Bacteria are not killed by d) adaptation hand sanitizer e) resistance 4) Camouflage of insect keeps it safe 5) More camouflage insects survive and reproduce

13. 6) What is co-evolution? 7) Describe how an organism must FIT its environment.

14. 8) One of the conditions for natural selection is “Individuals vary in fitness, or reproductive success” Explain what that means.

15. Warm Up 32 1) Explain what an adaptation is and how “NATURE SELECTS?”

16. 2) One of the conditions for natural selection is “Individuals vary in fitness, or reproductive success” Explain what that means.

17. 3) Explain what resistance is, and why it is a problem?

18. Warm Up 33 1) What does this diagram show us?

20. Warm Up 34 • Which “beak” was best for: • Pennies • Sand • Water 2) How is this lab a demonstration of survival of the fittest (natural selection)? 3) What happens to a species if it is unable to adapt to changes in its environment?

21. What do you know about the following terms: • Predator • Prey • Parasite • Herbivore • Mutualism

22. Warm Up 35 1) Copy the chart below. For the species indicate either positive (+), negative (-) interaction, or no impact (o).

23. 2) Explain how mutualism and commensalism are different from each other. 3) How are parasitism, herbivory and predation similar?

24. Warm Up 36 (3 Questions) 1) Define the following terms and give example • Producer • Consumer • Herbivore • Carnivore • Omnivore • Decomposer

25. 2) Use an example to explain how you are solar powered. 3) Explain why photosynthesis is so important to life on Earth.

26. Warm Up 37 (7 Questions) • Explain what cellular respiration is

27. 2) In the food web below, give an example of: • Producer b) Primary Consumer c) Secondary Consumer 3) If there were 100 units of energy in the grass, by eating the grass how many unit of energy would the mouse have?

28. 4) In an ecosystem why are there so few owls compared to grass? 5) How do herbivores have an advantage on carnivores?

29. 6) Describe what some possible effects are if there is a disease killing off mice. 7) Which population would you expect to be: a) smallest, b) largest?

31. Warm Up 38 (3 questions) 1) Explain the diagram below.

32. 2) What is a pioneer species? 3) What is the difference between primary and secondary succession?

33. Warm Up 39 (5 Questions) 1) Explain how this diagram shows natural selection.

34. 2) Which is photosynthesis and which is cellular respiration? a) b)

35. 3) What does this diagram tell us about organisms in an ecosystem?

37. 4) Label a producer, primary consumer and a secondary consumer.

38. 5) What is the difference between primary and secondary succession?

39. Warm Up 40 1) Try to explain this chart.

40. 2) Explain this chart

41. 2) Why do you think these difference in NJ exist?

42. Warm up 41 1) What is a biome?

43. 2) What is the difference between weather an climate?

44. Warm Up 42 What is your biome? List 3 characteristics you think are important about your biome.

45. Warm Up 44 (4 Questions) 1) Explain what you see in the chart below

46. 2) What is biodiversity?

47. 3) What do you think happens to an ecosystem when a species goes extinct?

48. 4) Why does biodiversity increase as latitude decreases (closer to equator)?

49. Last Week You Learned… 1) There is a huge diversity of life on Earth that is critical to all species. 2) We call that variety of life BIODIVERSITY. 3) There are 3 types: ecosystem, genetic and species diversity. 4) Biodiversity is important for: food webs to function, medical reasons, ethical reasons and more VIDEO: HOW WE DISCOVER NEW SPECIES

50. Warm Up 45 • Why do you think some species go extinct? • What do you know about “mass extinctions?” • Do you think we should worry about other species going extinct? WHY?
