I'm not quite sure what the question you're asking is so let me know if I interpreted this correctly. You're given 3 factors that could be affecting the walleye, bull trout, gold eye, and white fish populations. They want to know whether these are biotic or abiotic factors.
BIOTIC factors are living things that affect the ecosystem. So if these harlequin ducks are eating the fish (decreasing the population), they're a biotic factor limiting the population.
ABIOTIC factors are non-living things that affect the ecosystem. The amount of oxygen in the water for the fish to breathe and the mercury levels (and potential mercury poisoning) are abiotic limiting factors.
