Question

which of these is an element that can bioaccumulate and lead to biomagnification? oxygen argon hydrogen mercury

Explanation:

Biomagnification occurs when substances like heavy metals (e.g., mercury) accumulate in organisms at higher trophic levels. Mercury is a heavy metal that can bioaccumulate (build - up in an organism) and biomagnify (increase in concentration up the food chain). Oxygen, argon, and hydrogen are common, non - toxic elements that do not bioaccumulate in a harmful way to cause biomagnification.

Answer:

mercury
