5 Matching questions

  1. per-capita availability
  2. age structure
  3. logistic carrying capacity
  4. demographic transition
  5. replacement level fertility
  1. a The 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
  2. b structure of a population divided into groups by age. Sometimes the groups represent the actual number of each age in the population; sometimes the group represents the percentage or proportion of the population of each age
  3. c the amount of a resource available per person
  4. d In terms of the logistic curve, the population size at which births equal deaths and there is no net change in the population
  5. e fertility rate required for a population to remain a constant level

5 Multiple choice questions

  1. average number of children expected to be born to a woman during her lifetime
  2. a group of individuals capable of interbreeding and producing fertile offspring
  3. the rate at which births occur in a population, measured either as the number of individuals born per unit of time or as the percentage of births per unit of time compared with the total population
  4. a disease that appears occasionally in the population, affects a large percentage of it, and declines or almost disappears for a while only to reappear later
  5. the continued growth of a population that occurrs after achievement of replacement level fertility is reached

5 True/False questions

  1. abortion ratethe estimated number of abortions per 1000 live births in a given year


  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. optimal carrying capacitythe 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


  4. populationa group of individuals capable of interbreeding and producing fertile offspring


  5. maximum lifetimegenetically determined maximum possible age to which an individual of a species can live
