Editing Biomagnification (section)

== Why This Works ==

''Biomagnification'' is when a substance, such as a toxin, is found in greater concentrations in organisms as you go up the food chain. Organisms at the bottom of the food chain typically are the first to eat the toxic substances, but because they individually ingest only small amounts, the effects of the toxin are not easy to spot or distinguish. When those organisms are eaten by something above them in the food chain, the toxins will collect in the larger organism, which can cause it to become ill. When those organisms are eaten by things above them in the food chain, the toxins continue to build up, and those animals toward the top of the food chain can suffer the most because of the buildup of toxins. The buildup can even result in the deaths of those animals at the top of the food chain, which can cause it to collapse. This is why pollution is bad, since the chemicals we put into the environment will eventually result in severe or even total destruction of the food chain.
