::clicker questions for Bio 109:: C 1. Given an equal sized overall starting population, which of the following societies would you expect to make the least overall demands on existing resources over the next two generations? (a) Bottom-heavy age structure (many young, few old), low per person ecological footprint (b) Bottom-heavy age structure (many young, few old), high per person ecological footprint (c) Top-heavy age structure (few young, many old), low per person ecological footprint (d) Top-heavy age structure (few young, many old), high per person ecological footprint (e) Evenly balanced age structure and sustainable use of natural resources on a per person basis B 2. Some farm-ranched salmon impose a cancer risk, because the smaller fish they are fed have pollutants in their fat, and thus they should be eaten no more than once every five months. Which of the following statements about this report is true? (a) Salmon biochemistry enlarges each pollutant molecule, a process known as biomolecular gigantism (b) Pollutants concentrate in salmon and then us during many meals by each predator, through biological magnification (c) Salmon biochemistry enlarges each pollutant molecule, a process known as biological magnification (d) This is a textbook case of optimal foraging and resource partitioning (e) Biological magnification permitted scientists to visualize individual pollutant molecules and study this problem C 3. Which of the following best describes the concept of carrying capacity? (a) The absolute number of organisms a habitat can support (b) The number of organisms a habitat can support, denoted by N, given a particular ecological footprint per organism (c) The number of organisms a habitat can support, denoted by K, given a particular ecological footprint per organism (d) The average mass of prey a predator can consume in one day, denoted by K (e) The population size, denoted by K, exhibited by the superior species under conditions of competitive exclusion B 4. Moving from the North Pole to the South Pole in the New World, which of the following represents a correct order in which the listed geographical attributes would be encountered (some biomes etc. are omitted)? (a) Polar ice, tundra, tropical rainforests, deserts, Equator (b) Polar ice, tundra, temperate grassland, tropical rainforests, polar ice (c) Tundra, polar ice, temperate grassland, Equator, tropical rainforests

(d) Coniferous forests, tundra, tropical rainforests, desert, Equator (e) Tundra, coniferous forests, tropical rainforests, desert, Equator E 5. The competitive exclusion principle states: (a) Speciation happens only in allopatry (b) Exclusive use of a habitat by one species is rare irregardless of resource abundance (c) Two species cannot indefinitely occupy the same niche if resources are unlimited (d) Three species cannot indefinitely occupy the same niche (e) Two species cannot indefinitely occupy the same niche if resources are in short supply E 6.
