2) The concentration of O2 will increase inside the cell.
The cell will want to reach equilibrium, meaning that there should be an equal number of oxygen inside and outside the cell. In the picture, more oxygen is shown outside the cell than inside so oxygen will flow into the cell until it has reached equilibrium. Therefore, the concentration of O2 will increase in the cell.
Hope this helps!!
What would most likely occur is that the organisms that eat salmon would have less food to eat and if their food supply, in this case, salmon were to run out, they would die or they would have to find something else to eat. If the organism that eats the salmon dies, in this case we'll call that organism, organism A, any other organisms that eat organism A will die or will have to find another means of food. So basically it causes a disruption in the food chain which can lead to the extinction of different species
