The table below shows the number of sharks caught at two stations in the gulf of mexico and the dissolved oxygen in the water at each station. what is the  most  likely reason for the low number of sharks caught at station 138?

The answer is the second option from the top: Anoxic waters create a harsh environment that does not support marine life.

Explanation: Looking at the table, the amount of dissolved oxygen water (which enables marine species to breathe underwater) at station 138 is 0.02mg/liter compared to 1.5mg/liter, much lower than at station 137. Anoxic means "lacking oxygen", which sharks need to survive. So a lack of oxygen in a particular region will limit the number of sharks able to survive or live in that region.
