Answer :

Biological Magnification is the increase in concentration of harmful substances in the body of the living organism at each trophic level.

Yes, the levels of this magnification is different at different levels of the ecosystem. It is highest at the topmost level of the food chain. As the chemicals like pesticides, DDT are non-degradable, these get accumulated progressively at each trophic level. As human beings occupy the top level in any food chain, the maximum concentration of these chemicals get accumulated in their bodies.
