5 Written questions

5 Matching questions

  1. abortion ratio
  2. population momentum or lag effect
  3. total fertility
  4. birth rate
  5. species
  1. a 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
  2. b a group of individuals capable of interbreeding and producing fertile offspring
  3. c the estimated number of abortions per 1000 live births in a given year
  4. d average number of children expected to be born to a woman during her lifetime
  5. e the continued growth of a population that occurrs after achievement of replacement level fertility is reached

5 Multiple choice questions

  1. 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
  2. genetically determined maximum possible age to which an individual of a species can live
  3. 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
  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. a group of individuals of the same species living in the same area or interbreeding and sharing genetic information

5 True/False questions

  1. 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

          

  2. age structurethe 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

          

  3. 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

          

  4. 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

          

  5. death ratethe 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
