Assuming all other factors are equal,a low biological oxygen demand would be likely to cause the
A)compensation point (or level)to rise in the lake.
B)compensation point (or level)to fall in the lake.
C)profundal zone to expand in the lake.
D)limnetic zone to shrink in the lake.

Question

Quizplus · Accepted Answer

Biological oxygen demand (BOD) is the amount of dissolved oxygen consumed by organisms in a body of water. A low BOD indicates that there is less organic matter present in the water, leading to a lower oxygen demand. With a lower oxygen demand, the compensation point (or level) would fall in the lake as the primary producers (i.e., phytoplankton) would require less dissolved oxygen to carry out photosynthesis. This may lead to a decrease in the size of the limnetic zone as less dissolved oxygen is available for fish and other aquatic organisms.
