Unformatted text preview: factors in controlling the growth rates of phytoplankton (D) make verifiable correlations of cause and effect between zooplankton and phytoplankton numbers (E) invent laboratory techniques that would have allowed them to bypass their field research concerning grazer control 24 2. Which of the following, if true, would call into question Hardy‘s principle of animal exclusion? (A) Zooplankton are not the only organisms that are affected by phytoplankton repellents. (B) Zooplankton exclusion is unrelated to phytoplankton population density. (C) Zooplankton population density is higher during some parts of the year than during others. (D) Net phytoplankton are more likely to exclude zooplankton than are nannoplankton. (E) Phytoplankton numbers can be strongly affected by environmental factors. 4. It can be inferred from the passage that one way in which many of the early researchers on grazer control could have improved their data would have been to (A) emphasize the effects of temperature, rather than of light, on phytoplankton (B) disregard nannoplankton in their analysis of phytoplankton numbers (C) collect phytoplankton of all sizes before analyzing the extent of phytoplankton concentration (D) recognize that phytoplankton other than net phytoplankton could be collected in a net (E) understand the crucial significance of net phytoplankton in the diet of zooplankton F or the following question, consider each of the 5. According to the passage, Hargrave and Geen did which of the following in their experiments? (A) They compared the grazing rates of individual zooplankton species in the laboratory with the natural grazing rates of these species. (B) The hypothesized about the population density of grazers in natural habitats by using data concerning the population density of grazers in the laboratory. (C) They estimated the community grazing rates of zooplankton in the laboratory by using data concerning the natural community grazing rates of zooplankton. (D) They estimated the natural community grazing rates of zooplankton by using data concerning the known population density of phytoplankton. (E) They estimated the natural community grazing rates of zooplankton by using laboratory data concerning the grazing rates of individual zooplankton species. choices separately and select all that apply 3. The author would be likely to agree with which of the following statements regarding the pressure of grazers on phytoplankton numbers? A □ Grazing pressure can vary according to the individual type of zooplankton. B □ Grazing pressure can be lower in nutrient-poor lakes than in bog lakes. C □ Grazing tends to exert about the same pressure as does temperature. 25 The belief that art originates in intuitive rather than 6. The passage suggests that which of the following rational faculties was worked out historically and would most likely have occurred if linear perspective philosophically in the somewhat wearisome volumes of and anatomy had not come...
