2. The separation of an organism’s habitat such that the species or population is kept separate

3. What is Habitat Fragmentation?

4. It is an example of a “natural cause” of habitat fragmentation

5. What is a Volcanic Eruption, a Flood, or a Fire caused by a Lightning Strike?

6. The term to describe too many organisms becoming overcrowded in small patches of territory

7. What is Crowding of the Arc?

8. 3,000

9. What is the number of invasive species in Canada?

10. A non-native species whose intentional or accidental introduction negatively impacts the natural environment

11. What is an Invasive Species?

12. Abiotic conditions within which a species can survive

13. What is Tolerance Range?

14. Non-living factors in the ecosystem such as temperature, pH, sunlight availability and wind direction

15. What is an Abiotic Factor?

16. Damming rivers and draining wetlands can change the availability of this abiotic factor

17. What is Water?

18. An organism living in a desert would likely have to be adapted to this hot abiotic factor

19. What is Temperature?

20. The needle on a cactus help reduce water loss from the plant. This evolutionary adaptation offsets this abiotic factor present in deserts that would increase water loss.

21. What is Wind?

22. Canada’s largest terrestrial biome

23. What is the Boreal Forest?

24. Large geographical region defined by climate (e.g., precipitation, temperature) with a specific set of biotic and abiotic features

25. What is a Biome?

26. Canada’s biome with little precipitation, extreme cold temperatures and small plants.

27. What is Tundra?

28. Canada has this type of rainforest biome on the west coast

29. What is Temperate Rainforest?

30. Biome characterized by low precipitation, large range of temperatures (hot and cold) and few trees

31. What is Grasslands?

32. Frogs require a wet habitat to survive. If conditions are too wet or too dry, frog populations decrease.

33. What is Tolerance Range?

34. The zone of the atmosphere where life occurs

35. What is Troposphere?

36. A healthy savannah contains a mix of zebra, giraffe, wildebeest, hyena, lion, gazelle and other animals.

37. What is Biodiversity?

38. A complex biotic community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region

39. What is a Biome?

40. Pigs happily eat worms or apples.

41. What is an Omnivore?

42. Ingestion, inhalation and diffusion are the processes that contaminants enter your body

43. What is Bioaccumulation?

44. A process in which chemical substances become more concentrated at each higher trophic level. Such chemical substances tend to be difficult to be removed from animal and plant tissues.

45. What is Biomagnification?

48. Excessive aquatic plant growth

49. What is Hyper-eutrophication?

50. The accumulation of a chemical in the tissues of an organism as a result of direct exposure to the surrounding medium. NOTE: it does not include food web transfer.

51. What is Bioconcentration?
