EXAM 3 ASU BIO REAL NEWEST EXAM VERSION |182 QUESTIONS AND ANSWERS GRADED A 1. Which group is not a population ?: all four groups are populations 2. How would you estimate the number of whales in a population?: mark and recapture 3. What is a population?: a group of individuals of the same species living in the same area at the same time 4. True or False? Sampling quadrats would be the better method for estimating the number of whales in a population.: false 5. True or False? Mark and recapture would be the better method for estimating the number of saguaros in a p opulation.: true 6. True or False? The shrinking population between 1965 and 1970 could have resulted from a decrease in the birth rate or an increase in the death rate.: true 7. True or False? The growing population between 1985 and 1995 could have resulted from a decrease in emigration or an increase in immigration .: true 8. The human population has grown : exponentially 9. The growth of a population depends on : the birth rate minus the death rate. 10. A population stops growing when it : reaches its carrying capacity . 11. True or False? The carrying capacity of a population depends on the resources available in the environment .: true 12. Why do bluegills nest on the edge of the lake?: The habitat in the shallow water might receive more solar radiation, ho lds more zooplankton (which is what they eat), more protective over young than it in deeper water where larger fish reside, more algae for the fish to hide in, warmer water for embryos to develop quickly and enhance survival/fitness. 13. Activity: Write a Figure Legend: Bluegills prefer certain water temp; when given a choice between 27 degrees celsius and 31 degrees celsius, bluegills spent a majority of their time at 31 degrees celsius. 14. True or False? If males compete for space, a large male will likely force a small male to spend less time on the side of the tank with the optimal temperature .: true 15. True or False? Both models assume that no individuals immigrate into the population.: false 16. t/f: When possible, a bluegill prefers to have a body temperature around 31°C.: true 17. T/F: When competing with an adult, a juvenile bluegill will always have a lower body temperature than its preferred temperature.: False (If the environ - EXAM 3 ASU BIO REAL NEWEST EXAM VERSION |182 QUESTIONS AND ANSWERS GRADED A ment hotter than preferred, on average, large bluegill will force small bluegills to remain in parts of water that are hotter than preferred) EXAM 3 ASU BIO REAL NEWEST EXAM VERSION |182 QUESTIONS AND ANSWERS GRADED A 18. T/F: All else being equal, the carrying capacity of a lake would likely increase as more parts of the lake warm to 31°C.: true 19. T/F: All else being equal, a juvenile bluegill will likely grow slower in a lake with many adult bluegills than in a lake with few adults: true 20. T/F: The growth of a bluegill population would be better described by a model without density dependence than by a model with densit y depen - dence.: false, Because access to suitable temperatures is limited, the growth of the population will have a carrying capacity, which requires density dependence 21. T/F: The number of whales was more likely estimated by sampling than by mark -recapture.: false 22. T/F: The shrinking population between 1965 and 1970 could have resulted from a decrease in the birth rate or an increase in the death rate.: true 23. T/F: The growing population between 1985 and 1995 could have resulted from a decrease in emigration or an increase in immigration.: true 24. T/F: Between 2005 and 2008, the sum of the birth and immigration rates roughly equaled the sum of the death and emigration rates.: true 25. T/F: The growth of this population would be described well by an exponen - tial model.: false 26. in 1904, Joseph Grinnel argued that "Two species of approximately the same food 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 environ - ment if they require identical resources.: competitive exclusion principle 27. T/F: The model of competition between species can ignore competition within species: false 28. T/F: The larger the competitive effect on a species (alpha or beta), the more likely the species will persist during competition.: false 29. T/F: When two species have different niches, the competition coefficients (alpha and beta) are likely to be less than 1.0.: true 30. T/F: If two species compete, neither species will reach its carrying capacity before one of the species goes extinct.: true 31. T/F: The rate of population growth (r) determines whether a species can persist during competition.: false 32. T/F: A realized niche is usually larger than a fundamental niche: false 33. True or False? Competing species are more likely to coexist if their growth rates (r1 and r2) increase.: false 34. True or False? Paramecium are most likely to persist at intermediate
