Which of the following claims is best supported by the data shown in the table above?A The owl population experienced increased mortality from 2010 and 2015 because of small prey populations. 1 / 2
B The owl population experienced population overshoot between 1995 and 2000 because of increased competition for resources.C The mouse population experienced increased fecundity between 2000 and 2005 because of declining resources.D The mouse population experienced zero population growth between 1985 and 1990 because of the large number of predators. - ANS✅B: The owl population experienced population overshoot between 1995 and 2000 because of increased competition for resources.
The following age structure diagrams were created for various counties in the United States from 2000 census data.In a given country, the population size is decreasing because there are fewer pre-reproductive-aged individuals in the population. Which of the age structure diagrams best illustrates the population of this country? - ANS✅A - inverted pyramid (declining population): the population is most likely declining because of increased women education which delays the reproductive age of women, and therefore lowers their total fertility rate (TFR)
The following age structure diagrams were created for various counties in the United States from 2000 census data.Which of the following statements best describes the pattern seen in age structure diagram C?A The county has very little difference between the number of individuals in younger age groups and in older age groups, indicating a declining population size.B There is an imbalance between males and females, with a ratio of 1.5 men to every woman in the population.C The county most likely has a total fertility rate of less than 2.0.
