In an agricultural farm, DDT was used to kill insects. Unfortunately, the amount of DDT used was very high and when there was rainfall, it was taken to the nearby lake along with the rainwater and got accumulated there. Given below is a food chain operating in this lake ecosystem: Phytoplankton → zooplankton → fish → aquatic bird In which organism's body the concentration of DDT will be highest?
