Fish must have oxygen for survival. A decrease in oxygen would decrease the  number of fish.

The correct answer to this question is D.

What is oxygen?

Oxygen is an element that is very necessary for the survival of living things. Every living thing has the need for oxygen so that they would be able to survive. Living things breathe in oxygen and they breathe out carbon dioxide.

When there is no oxygen in the water, this would make survival difficult for the fishes in the water leading to their deaths.
