Question

an environmental watch group tells the public to avoid eating certain fish due to their high levels of bioaccumulated contaminants. the list includes fish such as albacore tuna, swordfish, and orange roughy. what can you infer about these fish species?
a the contaminants are particularly toxic to their favorite prey
b they inhabit areas that are frequently polluted by the oil industry
c they are filter feeders that consume nutrients floating in water
d they are large predators located high on the food chain

Explanation:

Bioaccumulation and biomagnification mean contaminants build up in organisms, with higher concentrations at higher trophic levels (top of the food chain). Albacore tuna, swordfish, and orange roughy are large predators high on the food chain, so they accumulate more contaminants than lower trophic level organisms. Options A, B, and C do not align with the mechanism of biomagnification linked to these species.

Answer:

D. They are large predators located high on the food chain
