- Why is the world population increasing? Select one: a. Women in developing countries are continuing to have more children, thereby increasing the global fertility rate. b. Advances in medical technology are allowing the world population to live longer and decrease infant mortality. c. The global birth rate is continuing to surpass the death rate. d. A significant portion of the global population is getting older and retiring earlier.arrow_forwardAll of the following conclusions can be made about the population represented in the above age pyramid EXCEPT Select one: a. the wide base indicates a high birth rate b. death rates are only high in extreme old age c. the steep sides show the death rate is high for both the young and adults d. life expectancy is low with few people reaching old agearrow_forwardWhich of the following statements about exponential growth is FALSE? O a. Increases in the size of the population do not affect per capita rate of increase (r). Ca. b. Exponential growth adds a constant number of individuals per unit time to a population as N gets larger. C. In reality, it is not possible for exponential population growth to continue indefinitely. d. In an exponentially growing population, the % increase of the population per unit * time doesn't depend on the number of individuals (N) in the population.arrow_forward
- Growth rate of a population is determined by: A. The increase in the number of people per unit of time. B. The number of people being born minus the number of people dying. C. The number of children living per each two adults. D. The number of people times the number of children each one has per year.arrow_forwardPopulation growth is exponential for the human population. It is an example of a positive feedback cycle where with each child born, the potential number of parents increases in the future. What is the most logical conclusion as to when the human population will reach its carrying capacity? A. When a regulating factor exists that keeps the population at equilibrium B. When feedback mechanisms kick in and population growth declines below carrying capacity C. When equilibirum is reached D. When density-dependent factors come into play and population levels start to decline ❌arrow_forwardWhen discussing population size, we are referring to a. the total number of individuals in a population. b. the size of the geographic region in which a population is found. c. the number of individuals in a population divided by the area of the region covered by the population. d. the number of individuals in a population multiplied by the area of the region covered by the population. e. the specific type of environment in which a population can exist.arrow_forward
- Which statement about population growth is true? A. Population growth models do not apply to humans. B. Population growth can be exponential for only as long as environmental conditions are favorable. C. Population growth can continue indefinitely. D. Population growth of field samples always has a λ of approximately 1.arrow_forwardThe world population reached seven billion in 2011. At current growth rate, it is expected to reach eight billion by 2024 and nine billion by 2037. However, many projections predict that the world population will level off at around 9 billion individuals. Why is the world population expected to level off? Select one: a. The global fertility rate has been decreasing for the past 20 years and is expected to decline even further. b. More than a third of the world population is expected to be aged 60 years or above in 2100. c. The Earth’s carrying capacity is estimated at 9 billion individuals, when the global birth rate and death rate become equivalent. d. Recent technological and medical advances led to increased life expectancy, allowing individuals to live longer.arrow_forwardJapan currently exhibits which of the following age-structures (population profiles)? A. the column population profile B. the inverted pyramid population profile C. the bulge population profile D. the pyramid population profile E. all of the abovearrow_forward

A. Density-dependent factors are more harmful. B. Density-independent factors affect the population despite the density. C. Density-independent factors are more harmful.arrow_forwardGiven that fertility rate is defined as each woman producing exactly enough offspring to replace herself and her offspring’s father, if the fertility rate is sustained for a generation, then which of the following is true? Select one: a. r > 1 b. 0 < r < 1 c. r = 0 and there is zero population growth d. r = 1arrow_forward
