In а biоmаgnificаtiоn situatiоn, assume that a dangerous chemical, called "X" is present in the water of a small bay at a concentration of .00005 parts per million (ppm). Also assume there are three layers of consumption between the water and a certain predatory bird that lives around the lake, and at each step of consumption, chemical X gets magnified 1000 times. What is the final concentration of chemical X in the predatory bird after eating 100 fish in a week?
