- The following statements are true except a. Founder-controlled communities are those in which there are species that has theability to invade gaps and competitors that can hold the gaps against all comersduring their lifetimeb. Dominance-controlled communities are those in which some species arecompetitively superior to others so that an initial colonizer of a patch cannotnecessarily maintain its presence therec. Primary successions occur in habitats where no seeds or spores remain from theprevious occupants of the site; all colonization must be from outside patchd. Secondary successions occur when existing communities are disturbed but someat least of their seeds and so on remain.. SCIENTIFIC INQUIRY You are testing the hypothesis thatincreased population density of a particular plant speciesincreases the rate at which a pathogenic fungus infectsthe plant. Because the fungus causes visible scars on theleaves, you can easily determine whether a plant is infected.Design an experiment to test your hypothesis. Describe yourexperimental and control groups, how you would collect data,and what results you would see if your hypothesis is correct.Explain how the three major types of deserts differin their climate and vegetation.

- How can a great biologicaldiversity protect an ecosystemfrom environmental damage?Why are less biodiverseecosystems at risk of sufferingdeep biological harm ifsubmitted to even smallchanges?SCIENCE, TECHNOLOGY, AND SOCIETY Some people regardthe rapid population growth of less industrialized countries asour most serious environmental problem. Others think that thepopulation growth in industrialized countries, though smaller,is actually a greater environmental threat. What problems resultfrom population growth in (a) less industrialized countriesand (b) industrialized nations? Which do you think is a greaterthreat, and why?Perhaps 98 percent to 99 percent of all species that have ever existed areextinct. Nearly all went extinct long before humans arrived on the scene. Whyshould we be concerned about the extinction of organisms today?
- With antibiotic resistance rising, researchers are lookingfor ways to reduce use of these drugs. Some cattle oncefed antibiotic-laced food now get probiotic feed that canbolster populations of helpful bacteria in the animal’sgut. The idea is that if a large population of beneficialbacteria is in place, then harmful bacteria cannot becomeestablished or thrive. Which ecological principle is guiding this practice?2. The emergence of mayflies from a stream that are consumed by bats that live in the forest is an example of how ecosystems:a. have diffuse boundariesb. don’t interactc. are synergisticd. all of theseThe Barton Springs salamander is an endangered species found only inthree adjacent springs in the city of Austin, Texas. There is growingconcern that a chemical spill on a nearby freeway could pollute thespring and wipe out the species. To provide a source of salamanders torepopulate the spring in the event of such a catastrophe, a proposal hasbeen made to establish a captive breeding population of the salamanderin a local zoo. You are asked to provide a plan for the establishment ofthis captive breeding population, with the goal of maintaining as muchof the genetic variation of the species as possible. What factors mightcause loss of genetic variation in the establishment of the captivepopulation? How could loss of such variation be prevented? With theassumption that only a limited number of salamanders can bemaintained in captivity, what procedures should be instituted to ensurethe long-term maintenance of as much variation as possible?

Which statement(s) correctly describe the graph? (Check all that apply.) The two species with highest levels are both fish.The two species with highest levels are both fish. Turtles had a pollutant level about three times that of clams.Turtles had a pollutant level about three times that of clams. No invertebrate (excludes fish and turtles) had a level above 0.05 ppm.No invertebrate (excludes fish and turtles) had a level above 0.05 ppm.
