ASU Bio 182 Exam 3 Questions and Answers Rated A+ T/F: The growth of a bluegill population would be better described by a model without density dependence than by a model with density dependence. false, Because access to suitable temperatures is limited, th e growth of the population will have a carrying capacity, which requires density dependence T/F: The number of whales was more likely estimated by sampling than by mark -recapture. false T/F: The shrinking population between 1965 and 1970 could have resulte d from a decrease in the birth rate or an increase in the death rate. true T/F: The growing population between 1985 and 1995 could have resulted from a decrease in emigration or an increase in immigration. true T/F: Between 2005 and 2008, the sum of the bi rth and immigration rates roughly equaled the sum of the death and emigration rates. true T/F: The growth of this population would be described well by an exponential model. false in 1904, Joseph Grinnel argued that "Two species of approximately the same f ood habits are not likely to remain long evenly balanced in numbers in the same region. One will crowd out the other." This idea became known as________. we can say that two species cannot coexist in the same environment if they require identical resources . competitive exclusion principle T/F: The model of competition between species can ignore competition within species false T/F: The larger the competitive effect on a species (alpha or beta), the more likely the species will persist during competition. false T/F: When two species have different niches, the competition coefficients (alpha and beta) are likely to be less than 1.0. true T/F: If two species compete, neither species will reach its carrying capacity before one of the species goes extinct. true T/F: The rate of population growth (r) determines whether a species can persist during competition. false T/F: A realized niche is usually larger than a fundamental niche false True or False? Competing species are more likely to coexist if their growth ra tes (r1 and r2) increase. false True or False? Paramecium are most likely to persist at intermediate temperatures? false Activity: Write a figure legend Video: How competing Species coexist C Paramecium went extinct when competing with compendium at 26 deg rees, but persisted at 22 degrees and 30 degrees. T/F: The number of replicates for each treatment equals the total number of lizards on both plots. false Which group is not a population? all four groups are populations How would you estimate the number of whales in a population? mark and recapture What is a population? a group of individuals of the same species living in the same area at the same time
