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: 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: 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: openstax.org/details/books/bi...

You can explain this better than my biology teacher could in an hour

You should take my biology class, Lorelai. Its 90 minutes, not an hour.....

[@Sam-nx6mo]

Right

[@crescentic_arts]

Every science student need a teacher like this

[@toadrules4658]

I'm not ashamed to admit I laughed at this video at several points. I love when my teachers say "Okay, so now we're going to watch an Amoeba Sisters on this!" It just makes my day. Thanks for making school more interesting.

[@NoWarInBaSingSe]

I wish our teacher was like your teacher. Our teacher opens the ppt of the chapter and just reads the text like a robot.

[@chawiss]

​@@NoWarInBaSingSeyooo my teacher give me this today

[@darrenjohnston6546]

I'm sharing this on social media because it is easier than attempting to explain to people what is wrong with DDT. I doubt they will watch it.

[@dinomoviesnstuff]

Saying ecology is a career for the brave and bold really hits home. Thank you and God bless!

[@jayden_mtb]

Why do we actually have to watch this stuff at school like if you hate school ->

[@ines..4530]

this isn't tiktok, the buttons are at the bottom

[@thechaosgardener]

Showing this in my biology class. Thanks!

[@ShenLong33]

Really, really love your videos. I'm chemist but i love all science, that includes biology. So, i really learn a lot from topics i dont know of biology. Thanks! =)

[@thateuphonistinthecorner5846]

If only actual science teachers were like you and Vsauce. They wonder why we don't like school...

Great video! The natural consequence of this info is for humans to eat lower on the food to reduce the pesticide load we get from food along with things like heavy metals, dioxins, perfluorochemicals, flame retardants and other pollutants!

[@elvzzz7776]

thankyou sososos much, ive watched neaarly all your videos and you might as well be the reason i pass science. you explain ssososso well and you are literally AMAZING at what you do!!!!!!!!!!!!!!!!!!!!!!!!!!!!1 thankkyyouuuuuu ssososososoos muccchhhhh, i couldnt be more gratefull

What is the difference between bioaccumulation and biomagnification?

They have the same meaning. They get bigger. But the only difference is that they are different words.
