I put 4 is 40 times less than 160, and so it isn’t proportional on the other bit (forgot what it was)

I've it is inversely propotional. Because as the number bacterias increases, oxygen level decreases. That's because bacterias respire by using oxygen to respire. Also Sewage causes algae to grow and block light leading to lack of oxygen in river water
