5 Matching questions

  1. age structure
  2. logistic growth curve
  3. epidemic disease
  4. abortion ratio
  5. birth rate
  1. a 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
  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 estimated number of abortions per 1000 live births in a given year
  4. d 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. e 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

5 Multiple choice questions

  1. a population in which the number of births equals the number of deaths so that there is no net change in the size of the population
  2. the estimated number of abortions per 1000 women aged 15 to 44 in a given year
  3. 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
  4. 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
  5. the study of populations, especially their patterns in space and time

5 True/False questions

  1. replacement level fertilityfertility rate required for a population to remain a constant level

          

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

          

  3. per-capita availabilityaverage number of children expected to be born to a woman during her lifetime

          

  4. total fertilityaverage number of children expected to be born to a woman during her lifetime

          

  5. optimal 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
