D. survive to adulthood Its habitat can support It produces at one time It actually produces over its lifetime Students type their answers here 2 In cases of exponential growth rates, a population ________ each year. A. Increases at the same rate B. Is multiplied by a constant number C. Doubles D. Triples E. Increases by a constant number (one, ten, one hundred, etc.), depending on the system Students type their answers here 3 Exponential growth would be represented by a ____ curve? A. B. C. D. E. J-shaped S-shaped straight bimodal linear Students type their answers here 4 Carrying capacity is the population or biomass A. B. C. D. E. That an environment can support in an optimal year Of a species that an environment can support on a long-term basis That remains after a catastrophic dieback has occurred Of a species without limiting factors Of a species without predators Students type their answers here 5 In the real world, population explosion is usually followed by A. B. C. D. E. A continuation of high population levels indefinitely A gradual decrease in population as food supplies dwindle A tremendous increase in genetic diversity A gradual increase in population due to the availability of mates A population crash Students type their answers here 6 A dieback or population crash, often occurs after a species ________ its environmental carrying capacity. A. B. C. D. E. Meets Undershoots Overshoots Oscillates around Decreases Students type their answers here 7 An island has formed off the coast of the Pacific Northwest. The Department of Natural Resources (DNR) has determined that there is enough land area for a herd of 100 elk, yet they say the carrying capacity is only 60 elk. This inequality can best be explained by the fact that the A. DNR is probably being careful not to overestimate B. DNR must have added up the environmental resistance incorrectly C. Elk population will probably fluctuate between 60 and 100 animals D. Physical factor of space is only one of the determiners for population size in a community E. Law of limiting factors determines the maximum growth rate for a given population Students type their answers here 8 Which of the following types of population growth patterns would best represent a group of elephants that enter a new, open habitat and become a stable part of that ecosystem? A. B. C. D. E. Exponential growth Irruptive growth Malthusian growth Chaotic or catastrophic growth Logistic growth Students type their answers here 9 Which of the following types of population curves would best represent a group of elephants that enter a new, open habitat and become a stable part of that ecosystem? A. B. C. D. E. Norm-shaped curve S-shaped curve J-shaped curve Cyclic oscillation-shaped curve Survivorship curve Students type their answers here 10 Widespread starvation is an example of _________ population control. A. B. C. D. E. Predator-caused Biotic Density-dependent Density-independent Abiotic Students type their answers here 11 You are studying an organism that is an opportunistic pioneer species and does not care for its offspring. This organism probably has a(n) _________________ population growth strategy. A. B. C. D. E. K-adapted R-adapted Irregular Catastrophic R-adapted and irregular Students type their answers here 12 You are studying an organism that is fairly large, matures slowly, lives fairly long, and cares for its offspring. This organism probably has a(n) _________________ population growth strategy. A. B. C. D. E. K-adapted R-adapted Irregular Catastrophic R-adapted and irregular Students type their answers here 13 When the similarities in population increases and decreases in prey and predators, it lead us to the conclusion that A. species. B. C. D. species. The abundance of both the prey and predator can affect the other The abundance of only the prey species can affect another species. The abundance of only the predator species can affect another species. There is no relationship between the abundances of predator and prey Students type their answers here 14 Life expectancy is the A. Maximum life span that an individual of a given species could reach B. Number of individuals in a population that survive in a given year C. Number of years an individual of a certain age will probably live D. Probability that an individual will survive infancy E. All of these are descriptions of life expectancy Students type their answers here 15 Survivorship is determined by A. B. C. D. E. The percentage of a cohort that survives to a certain age The number of individuals in a population that survive in a given year The number of years an individual of a certain age will probably live The probability that an individual will survive infancy The maximum life span that an individual of a given species could reach Students type their answers here 16 If there is no migration, the size of a population is limited solely by interaction between A. B. C. D. E. Natality and fertility Mortality and fecundity Mortality and survivorship Natality and mortality Life expectancy and survivorship 17 Predation is considered to be a(n) _______________ factor. A. B. C. D. E. Extrinsic Intrinsic Abiotic Biotic Extrinsic and biotic Students type their answers here 18 Which of the following is an abiotic population control mechanism? A. B. C. D. E.
