candy represents the amount of DDT (in ppm) the algae ingested from pesticide runoff from a nearby agricultural area. There are 100 M&M’s in the pile. Each circle below represents on phytoplankton. Mark the amount of toxin each phytoplankton has ingested. If there is a full “M” stamped on the candy then that phytoplankton has ingested 1 ppm of DDT‚ so write “1” in one of the circles below. If there is no “M” on the candy then that phytoplankton did not ingest any DDT so write a “O” in one of the circles
