Biological Magnification is a phenomenon which explains the increasing concentration of harmful chemicals (like DDT) with increase in trophic level. From the soil the chemicals (mainly pesticides, heavy metals, etc.) are absorbed by the plants. The primary consumers eat these plants and the harmful chemicals enter their bodies. As these chemicals are not degradable, they accumulate in the bodies of the organisms and the top level of the food chain gets the highest concentration of these harmful chemicals. Levels of bio-magnification would increase as the trophic level increases and would be higher for higher trophic levels.
