Achemist is studying dissolved gases in the ocean. she graphs her data as shown below.

image of graph. x-axis is labeled concentration of dissolved gas in milliliters per liter (ml/l) and there are two scales on the x-axis. the scale labeled o2 starts at 44 and increases by 2 until it reaches 52. the scale labeled co2 starts at 1 and increase by 1 until it reaches 6. the y-axis has two labels and two scales. the label on the left y-axis is depth (m). the scale for depth (m) starts at the top of the graph at 0 and increases by 100 until it reaches 4000. the label on the right y-axis is depth (ft). the scale of depth (ft) starts at the top of the graph at 0 and increases by 4000 until it reaches 12,000. two lines appear on the graph. the red line, representing co2, starts at left hand side of the graph around 44 ml/l on the x-axis and 0 meters and 0 feet on the y-axis. the red line starts to shift to the right at about 500 m and 2000 ft. it continues to shift to the right as depth increases until it is constant at about 51 ml/l. the blue line, representing o2, starts at the right hand side of the graph around 6 ml/l on the x-axis and 0 meters and 0 feet on the y-axis. the blue line starts to shift to the left at about 300 m and 1000 ft. the blue line is nearly constant on the y-axis but shifts to the left on the x-axis from 5 ml/l to about 2 ml/l where it intersects with the red line at about 600 m and 2000 ft. the blue line then stays constant at 2 ml/l as depth increases from 600 m and 2000 ft to 3000 meters to 10,000 ft. it then shifts back to the right just past the 2 ml/l mark on the x-axis and stays constant as depth increases to almost 4000 m and 12,000 ft.

explain the trend shown in dissolved oxygen and carbon dioxide versus depth, and then predict where organisms that rely on high oxygen concentrations would live. justify your answer by using the data provided.

i have no idea
