5 Written questions

5 Matching questions

  1. age dependency ratio
  2. species
  3. death rate
  4. population momentum or lag effect
  5. abortion ratio
  1. a the continued growth of a population that occurrs after achievement of replacement level fertility is reached
  2. b the estimated number of abortions per 1000 live births in a given year
  3. c a group of individuals capable of interbreeding and producing fertile offspring
  4. d The rate at which deaths occur in a population, measured either as the number of individuals dying per unit time or as the percentage of a population dying per unit time
  5. e the ratio of dependent-age people (those unable to work) to working-age people; it is customary to define workin-age people as those aged 15-65

5 Multiple choice questions

  1. the maximum number of human beings which can live on Earth at the same time; is dependent on the quality of life people desire and are willing to accept
  2. fertility rate required for a population to remain a constant level
  3. the maximum abundance of a population or species that can exist in an ecosystem without degrading the ability of the ecosystem to maintain: (1) that population of species; (2) all necesary ecosystem processes; (3) the other species found in that ecosystem
  4. the amount of a resource available per person
  5. average number of children expected to be born to a woman during her lifetime

5 True/False questions

  1. logistic carrying capacitythe maximum abundance of a population or species that can exist in an ecosystem without degrading the ability of the ecosystem to maintain: (1) that population of species; (2) all necesary ecosystem processes; (3) the other species found in that ecosystem

          

  2. logistic growth curveThe net increase of some factor per unit time. In ecology, the growth rate of a population is sometimes measured as the increase in numbers of individuals or biomass per unit time and sometimes as a percentage increase in numbers or biomass per unit time

          

  3. human demographythe study of populations, especially their patterns in space and time

          

  4. growth rateThe net increase of some factor per unit time. In ecology, the growth rate of a population is sometimes measured as the increase in numbers of individuals or biomass per unit time and sometimes as a percentage increase in numbers or biomass per unit time

          

  5. demographic transitionThe pattern of change in birth and death rates as a country is transformed from undeveloped to developed. THere are three stages: (1) in an undeveloped country, birth and death rates are high and the growth rate is low; (2) the death rate decreases, but the birth rate remains high and the growth rate is high; (3) the birth rate drops toward the death rate and the growth and the growth rate therefore also decreases
