Biological Magnification
The increase in concentration of harmful substances in the higher levels of a food chain
Real World Example
Imagine you’re at a potluck dinner where each person brings a dish to share, but one dish contains far too much salt. As everyone samples a little bit of each dish, that salty dish remains mostly untouched until one person decides to finish it all. This is similar to biological magnification, where small amounts of a harmful substance, like a pesticide, accumulate in organisms at the bottom of the food chain but become highly concentrated in predators at the top. Just as the last person at the potluck ends up consuming most of the salt from that single dish, top predators accumulate higher concentrations of toxins because they consume so many contaminated organisms from lower levels in the food chain.
