Thus it is the organisms at the highest trophic level that are the most affected. This accumulation occurs because the organisms have not evolved enough to posess mechanisms that <em>facilitate detoxification of various substances. </em>
Such substances are called novel substances and DDT is an example. Removal of substances like metals is also difficult. Thus a harmful chemical component travels up various trophic levels increasing in <em>concentration at each trophic level.
