Why do you think mercury concentrations may be highest in organisms at the top of the arctic food chains

because mercury accumulates as it climbs up the food chain
an animal that eats others collects all the mercury those animals it has eaten, and then in the next stage of the food chain, the animal that ate that one will acumulate all the mercury it has eaten as well

mercury is difficult to expel from the body
