The purpose of this experiment is to show how dichloro-diphenyl-trichloroethane, a synthetic pesticide, moves through the food chain. The special focus of this experiment is how dichloro-diphenyl-trichloroethane (DDT) bioaccumulates and energy moves through the trophic levels of a food chain. To illustrate biomagnification, M&M chocolates were used to exemplify phytoplankton with the opacity of the M mark on the chocolate serving as the amount of DDT within the phytoplankton. For example, an M&M with a perfect M mark on it was said to be a phytoplankton that ingested one hundred percent of the DDT while an M&M with an absent M mark on it was said to be a phytoplankton with zero percent DDT ingestion. Amount of DDT, measured in ppm, and kilocalories
