Keystone species c a. Genetic diversity d b. Biodiversity 3 Which of the following is needed in order to decrease the chances of a species going extinct? This gives a species a better chance of adapting to changing environments. a c. Small habitats b a. Low genetic diversity c b. High genetic diversity 4 Which of the following is why high biodiversity is important? a a. Results in a large and diverse food web b c. Neither answers are correct c b.

Natural predators b c. Invasive predators c a. Poaching 8 Are ecosystems healthier when there is a larger variety of organisms in each trophic level? a a. Yes, because there is greater biodiversity b b. No, because there are too few resources 9 Give an example of a disturbance that would cause primary succession and an example for secondary succession. a Primary: volcanic eruption; Secondary: wildfire b Primary: drought; Secondary: hurricane c Primary: flood; Secondary: earthquake 10 Describe what happens to the biomass levels as primary succession moves through the stages to a climax community. a Biomass increases b Biomass stays the same c Biomass decreases 11 How would you describe a climax community? a A community that rapidly declines b A stable, mature community with little change c A disturbed, early-succession community 12 Define primary succession. a Development that begins with established soil b Development that begins in a barren area with no soil c A rapid colonization by animals 13 Define secondary succession. a Development on bare rock with no soil b A slowing process with no change c Recovery after a disturbance where soil remains 14 Which takes longer to reach a climax community, primary or secondary succession? a Primary b Secondary 15 Which of the two, primary or secondary, starts with no useable dirt? a Primary b Secondary 16 Define pioneer species and give an example. a Pioneer species are the last to colonize barren environments; example: oak trees b Pioneer species are first to colonize barren environments; example: lichen c Pioneer species are always animals; example: rabbits 17 Describe the Theory of Island Biogeography. a Only island age matters b Climate alone determines species richness c Distance from mainland and island size affect species richness 18 Which island would have more species migrate to it? (Choose two of the following words.) Large, Small, Far from mainland, Close to mainland a Small and Close to mainland b Large and Close to mainland c Small and Far from mainland 19 Define biodiversity. a Only the number of species in an area b The variety of life in all its forms, levels, and combinations c The variety of ecosystems in an area 20 Define keystone species. a A species that is rare and inconspicuous b A species with a large population c A species whose impact on its ecosystem is disproportionately large relative to its abundance

You can integrate the game into an LMS compatible with LTI 1.1 or LTI 1.3 such as Canvas, Moodle, or Blackboard. This way, the scores will be automatically saved into the platform’s gradebook.
