  1. Biological Magnification http://waynesword.palomar.edu/images/ecology1.jpg

  2. Biological Magnification: • Increasing concentration of a substance (toxin) in organisms in higher levels of the food chain. http://1.bp.blogspot.com/-N7jSasBEwO0/USUeDncMJkI/AAAAAAAAAHQ/j3zUDvmo44Y/s1600/biomagnification+3.jpg

  3. What conditions are necessary for biological magnification to occur? Substance must be: • Able to be absorbed into food chain • Not easily broken down by environment • Difficult for organisms to break down or digest http://www.potosisd.k12.wi.us/staff/hutchcroft/Biology%20Notes/Power%20Presentations-Biology/assets/Transparencies/Biomagnification.gif
