  2. The number of individuals per unit area.

  3. What is population density?

  4. These 3 factors affect population size.

  5. What are # of births, # of deaths, and #entering or leaving?

  6. Under ideal conditions, populations grow this way.

  7. What is exponential growth?

  8. When resources become less available, this type of growth occurs.

  9. What is logistic growth?

  10. The largest # of organism that the environment can support.

  11. What is the carrying capacity?

  12. These cause population growth to decrease.

  13. What are limiting factors?

  14. These factors affect populations only when they reach a certain density.

  15. What are density-dependent limiting factors?

  16. Examples include weather, human activity, and natural disasters.

  17. What are density-independent limiting factors?

  18. Examples include competition, predation, and disease.

  19. What are density-dependent limiting factors?

  20. Parasites are this type of limiting factor.

  21. What is density-dependent?

  22. This kind of growth is represented by a J-shaped curve

  23. What is Exponential growth?

  24. 2 factors that caused human growth rate to become exponential.

  25. What are improved: agriculture, industry, transportation, sanitation, medicine, and health care ?

  26. Individuals move into a population

  27. What is immigration

  28. Individuals move out of a population

  29. What is emigration

  30. Splitting an ecosystem into smaller pieces

  31. What is habitat fragmentation

  32. The variety of organisms in the biosphere.

  33. What is biodiversity?

  34. Species of many kinds have provided these 3 things for us.

  35. What are food, medicine, and industrial products?

  36. Humans reduce biodiversity in these 3 ways.

  37. What are: altering habitats; overhunting; introducing toxic compounds into food; and introducing invasive species?

  38. Toxic compounds increase in organisms at higher trophic levels. This is:

  39. What is biological magnification?

  40. 3 examples of invasive species

  41. What are: zebra mussels, gypsy moth, Asian carp, honey- suckle, starlings, kudzu, etc.?

  42. When a species no longer exists.

  43. What is extinct?

  44. When a species is declining in numbers, and may become endangered.

  45. What is threatened?

  46. When a species in danger of extinction

  47. What is endangered

  48. What is the biggest threat to biodiversity?

  49. What is human activity?

  50. The factor that is measured during an experiment (what you find out).
