A) temperature B) light availability C) solute concentration D) all of the above 4) Wetlands are standing bodies of freshwater, just like lakes and ponds. However, wetlands are different from lakes and ponds because ________. A) wetlands have shallow water. B) wetlands have emergent vegetation. C) wetlands have oxygen-poor water. D) answers A and B both apply. E) answers B and C both apply. 5) Which of the following statements regarding turnover is true? A) In fall turnover, dense water at 4°C sinks and disturbs sediments in the benthic zone. B) In fall turnover, dense water at 4°C rises and disturbs sediments in the benthic zone. C) The surface water gets to 4°C only by cooling. D) Fall turnovers and spring turnovers are exactly the same. 6) A fish swimming into a bog environment in Ohio would likely have which of the following as its greatest physiological challenge? A) The low oxygen content would make it difficult for the fish to swim aerobically. B) The low nitrogen content would make it difficult for the fish to synthesize proteins. C) The high temperature would stress the fish by denaturing its proteins. D) The high water flow would make the fish expend more energy.

A) The high water flow would make the fish expend more energy. B) The low oxygen content would give the fish difficulty in swimming aerobically. C) The temperature change would stress the fish by denaturing its proteins. D) The change in water solute content would challenge the osmotic balance of the fish. 8) The carnivorous pitcher plant is successful in bog habitats because ________. A) it can tolerate lack of oxygen in the bog water. B) it can tolerate the high acidity of the bog water. C) it can gain nitrogen in an unusual way.

D) Grasslands have too little precipitation to support tree growth. 21) According to the latest hypotheses, why do evergreens predominate in cold environments? A) Evergreens begin photosynthesizing in early spring, even before the snow melts. B) Evergreens do not shed their leaves and thus do not need as many soil nutrients.
