Answer:
oxegyen dissolves into the ocean from the atmosphere
Explanation:
The surface water is usually saturated with oxygen
Answer:
C. The trout population decreases as oxygen levels decrease.
Explanation:
We can see that the relationship between the number of trout and time passed is decreasing from the graph on the right because its line is decreasing. From the graph on the left, we can see that oxygen is decreasing as time goes on. Thus, we can interpret that the trout population decreases as oxygen levels also decrease; a proportional relationship.
The other options are incorrect because we can actually see that for...
A; the population of whitefish actually decreases as oxygen levels also decrease.
B; the population of carp actually increases significantly as sewage levels increase.
D; the walleye population actually also decreases overall as sewage levels increase.
