Biological Magnification

Biological magnification is the increasing concentration of a toxin in organisms at higher levels of the food chain. This occurs when the substance is easily absorbed into the food chain, not easily broken down, and difficult for organisms to digest. Learn more through visuals and videos.

  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
