5 Written questions

5 Matching questions

  1. demography
  2. human demography
  3. epidemic disease
  4. logistic growth curve
  5. population age structure
  1. a the study of human population characteristics, such as age structure, demographic transition, total fertility, human population and environmental relationships, death-rate factors, and standard of living
  2. b the study of populations, especially their patterns in space and time
  3. c 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
  4. d the number of individuals or proportion of the population in each age clas
  5. e The S-shaped growth curve that is generated by the logistic growth equation. In the logistic, a small population grows rapidly, but the growth rate slows down, and the population eventually reaches a constant size

5 Multiple choice questions

  1. The 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
  2. the estimated number of abortions per 1000 women aged 15 to 44 in a given year
  3. the amount of a resource available per person
  4. 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
  5. The estimated average number of years (or other time period used as a measure) that an individual of a specific age can expect to live

5 True/False questions

  1. human 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. total fertilitya group of individuals of the same species living in the same area or interbreeding and sharing genetic information


  3. age dependency ratiothe estimated number of abortions per 1000 live births in a given year


  4. chronica disease that is usually present in a population, typically occurring in a relatively small but constant percentage of the population


  5. birth rateThe 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
