Answer:
The correct answer is synergism.
Explanation:
In synergism, two or more substances interact with each other and produce a greater combined effect than the sum of the effect produced by them separately. So in synergism two chemicals enhance their overall effect when works together. For example, when a cancer patient is given chemotherapy and radiation together it shows better results than when these two therapy are used separately.
So, in this case, X and Y chemicals individually have a limited effect on fish but when used together their combined effect becomes greater which becomes toxic to the fishes that show that it is an example of synergism.
Basic needs? I think that is correct.
