Bio-magnification
When non-degradable substances enter the food chain, they do not get metabolized or broken down and instead get transferred up the trophic levels of the food chain. During this process, they show an increase in concentration which is referred to as bio-magnification. This results in increased toxicity and may even be lethal. This phenomenon is well established for mercury and DDT.
