Biomagnification and the Trouble with Toxins

Explore biomagnification which can happen when toxins become more highly concentrated when moving up through trophic levels in the food chain. Uncontrolled use of DDT is used in video as an example. Learn why bioaccumulation can occur in high level consumers!

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky's certification and experience in teaching biology at the high school level. For more information about The Amoeba Sisters, visit: http://www.amoebasisters.com/about-us...

REFERENCES:

This video only briefly touches on DDT as an example of biomagnification. Learn more about DDT from the EPA: https://www.epa.gov/ingredients-used-...

We cover the basics in biology concepts at the secondary level. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook: https://openstax.org/details/books/bi...
