  1. Gallo’s Game Show Extravaganza H EnviSci Final Exam Review Chapters 8, 10, 11 & 12

  2. Which of the following would be considered a population? • A. People, cats, dogs, and fleas at the park • B. People at the park • C. People, rocks, dirt, dogs, cats and fleas • D. I have no clue what a population is…

  3. What are the 4 major characteristics of a population? • Size • Density • Dispersion • Age distribution

  4. What are the 3 dispersion patterns? • Random • Uniform • Clumped

  5. What are factors that limit the growth of a population collectively called? • Environmental resistance

  6. What is the rate at which a population would grow if it had unlimited resources? • Intrinsic rate of increase (r)

  7. What is the equation for determining population growth? • (birth + deaths) – (immigration + emigration) • (births + emigration) + (deaths-immigration) • (births + immigration) + (deaths – emigration) • (births + immigration) - (deaths + emigration)

  8. What is the capacity of a population for growth? • Biotic potential

  9. What are some characteristics of a population with high biotic potential? • Reproduce early in life, generalized niche, suitable habitat, favorable light, short generation times, reproduce frequently

  10. What is determined by the interplay of environmental resistance and biotic potential? • Carrying capacity

  11. What is the maximum size of population that an environment will support • Carrying capacity – determined by the interplay of biotic potential and environmental resistance

  12. What are the 3 phases of logistic growth? • Phase 1 – exponential • Phase 2 - slows down - Due to: BR decreases, DR increases, immigration decrease, emigration increases • Phase 3 – population stabilized, reaches carrying capacity

  13. Which of the following is not a risk associated with sexual reproduction? A. Females have to produces twice as many offspring to maintain the same number of young as asexually reproducing organisms (BECAUSE MALES DON’T REPRODUCE) • Increased chance of genetic errors and defects during the splitting and recombination of chromosomes • Courtship and mating rituals consume time and energy, can transmit disease, and can inflict injury on males competing for sexual partners • Provides for less genetic diversity in the offspring therefore giving them less of a chance of survival when env. condition change

  14. Density Independent or Density Dependent • Predation • DD

  15. Density Independent or Density Dependent • Competition • DD

  16. Density Independent or Density Dependent • Affects all populations equally regardless of size • DI

  17. Density Independent or Density Dependent • Fire • DI

  18. Biotic Potential or Env Res • Favorable conditions • BP

  19. Biotic Potential or Env Res • Low reproductive rate • ER

  20. Biotic Potential or Env Res • Specialized niche • ER

  21. Biotic Potential or Env Res • Inability to resist parasites and disease • ER

  22. Biotic Potential or Env Res • Generalized niche • BP

  23. r or k selected species • Many small offspring • r

  24. r or k selected species • Late reproductive age • k

  25. r or k selected species • Little or no parental care • r – unlike Mrs. GALLO!!!

  26. r or k selected species • Population fairly stable, at or near carrying capacity • k

  27. What is the type of relationship in which population size fluctuates slightly above and below carrying capacity? • Stable

  28. What is the type of relationship that shows no real pattern? • Chaotic

  29. What type of growth is represented by a J shaped curve? • Exponential – bacteria may exhibit this

  30. What is the scientific process of using statistical methods to estimate how much harm a particular hazard can cause to human health or the environment? • Risk assessment

  31. What are the 4 types of hazards? • Cultural/lifestyle choices • Biological • Chemical • Physical

  32. What causes malaria and what transmits it? • Plasmodium parasite • Transmitted by Anopheles mosquito

  33. What are the 3 principle types of chemical hazards? • Mutagens • Carcinogens • Teratogens • Only 2% of synthetic chemicals today have been tested to see if they are these 

  34. Which causes a change in DNA? • Mutagens

  35. What is a carcinogen? Give an example • Cigarette smoke, viruses, radiation, chemicals, may have a 10-40 year delay between exposure and cancer

  36. What are gender benders; chemicals that may disrupt the bodies hormone levels by mimicking the action of estrogen and disrupting the reproductive system by binding to hormone receptors? • HAAs – hormonally active agents

  37. What explains the high amount of DDT found in eagles (top of the food chain)? • Biological magnification

  38. Which statement is true? • A. All chemicals are unsafe • B. Natural chemicals are safe, synthetic chemicals are deadly • C. All chemicals are safe except the ones that cause cancer • D. Some chemicals, man made or natural are safe others are deadly

  39. Give the two indicators of overall health in a population. • Life expectancy and infant mortality • High LE and Low IM will produce the highest rate of population growth

  40. The average number of births a woman has in a population is known as? • Total fertility rate

  41. The crude birth rate is the number of births per _____ people. • 1000

  42. What are useful for predicting population momentum and comparing population growth between countries? • Age structure diagrams

  43. What is the possibility of suffering harm from a hazard that can cause injury, disease, economic loss, death, or environmental damage? • Risk

  44. What are the 3 age groups in age structure diagrams? • Pre reproductive • Reproductive • Post reproductive

  45. What are the 3 most populous countries on Earth (start with most)? • China, India, US

  46. What are the four stages of demographic transition? • Preindustrial, transitional, industrial, postindustrial

  47. What are the layers of the atmosphere? • Troposphere • Stratosphere • Mesosphere • Thermosphere

  48. Which layer contains the ozone layer? • Stratosphere

  49. What is the most abundant gas in the atomsphere? • Nitrogen

  50. What are two primary pollutants that eventually result in acid rain? • Nox and SO2
