Because these compounds are released into waterways and adsorbed to sediments on a daily basis, continued monitoring and the employment of strategies to reduce their presence are warranted. Thus, the purpose of this cha

This simplified concept of energy flow has, over the past 30 years, been thoroughly criticized and reformulated (Pimm 1982, Polis and Winemiller 1994).
