Biomagnification write this on paper
Biomagnification(Write this on paper!)

  • Concentration of pesticides increases along the food chain

  • Because each trophic level eats multiple “infected” organisms so it all adds up


Organic food no additives
“Organic” food = No Additives

Non-Organic

  • Fruits and Vegetables treated with pesticides (if you eat a lot of these then the pesticides build up)

  • Hormones given to dairy cows to produce more milk is passed along to the consumer (rBGH-treated cows have increased levels of a hormone that increases growth (IGF-1 Insulin growth factor)
