APES Unit 3 Progress Check MCQ 2023_with Complete solution Scientists collected data for 35 years on the populations of mice and owls in a given area. 1985: 2 owls, 800 mice born, 200 mice died 1990: 8 owls, 800 mice born, 300 mice died 1995: 30 owls, 400 mice born, 500 mice died 2000: 10 owls, 650 mice born, 475 mice died 2005: 14 owls, 625 mice born, 625 mice died 2010: 15 owls, 650 mice born, 550 mice died 2015: 16 owls, 575 mice born, 550 mice died 2020: 8 owls, 725 mice born, 450 mice died. Based on the trends shown in the table, in which of the following years was the owl population at carrying capacity? (Correct) - 2015 Scientists collected data for 35 years on the populations of mice and owls in a given area. 1985: 2 owls, 800 mice born, 200 mice died 1990: 8 owls, 800 mice born, 300 mice died 1995: 30 owls, 400 mice born, 500 mice died 2000: 10 owls, 650 mice born, 475 mice died 2005: 14 owls, 625 mice born, 625 mice died 2010: 15 owls, 650 mice born, 550 mice died 2015: 16 owls, 575 mice born, 550 mice died 2020: 8 owls, 725 mice born, 450 mice died. 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. 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. (Correct) - 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? (Correct) - 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)
