Document Summary
Match the following scenarios with the correct possible cause: Fish have lesions and dissolved oxygen levels were 7 ppm toxin from algaeovergrowth of algae and subsequent decomposition. Both fish and shellfish have died and oxygen levels are 2 ppm toxin from algaeovergrowth of algae and subsequent decomposition. One set of bottles (called dark bottles) is covered with foil before sealing and leaving overnight (24 hours) in the lake. Another set of bottles (called light bottles) are filled with lake water. However, these bottles are not covered with foil before incubating in the lake overnight. Select one: photosynthesis, respiration, respiration and photosynthesis. The correct answer is: c. respiration and photosynthesis. In a healthy aquatic ecosystem, ample photosynthesis occurs. Select one: time 0 or initial bottle filled with lake water but not incubated in lake, light bottle with lake water incubated for 24 hours, dark bottle with lake water incubated for 24 hours. Light bottle with lake water incubated for 24 hours.
