Biological Magnification

DSC_0166

 

Biological magnification is the increase in the concentration of a substance through the higher levels of the food chain. This may occur because the substance can’t be broken down by natural environmental processes, or simply cannot be excreted by an organism. For example, as smaller fish eat plankton that have absorbed mercury, they accumulate the mercury in their body and are not able to excrete it or break it down. When these smaller fish are eaten by larger fish, the concentration of mercury increases to even greater levels.
