Which types of species tend to dominate river ecosystems? How do conditions between fast-moving 'headwaters' (or sources) of rivers differ from slow-moving 'mouths' of rivers? Where are the majority of producers in a lake located? Where would you expect to find the largest food webs - oligotrophic, mesotrophic, or eutrophic lakes? Explain. What characteristic defines a wetlands? Why are wetlands so ecologically productive, and what valuable ecosystem services do they provide to humans? Where are coral reefs generally found, how are they built, and why are they under heavy threat from bleaching? Do the vast open oceans areas deeper than ~200 meters and away from coastlines support much life? Explain

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species
