Bioamplification is the process that results in increasing concentrations of toxins in the bodies of consumers at each increasing trophic level. This concept is involved with pesticides and food chains. Pesticides with chlorine content (DDT & Dieldrin), are soluble in fat, but not in water, as they build up in the fatty tissues of animals. "Even though, there is only a small amount of the toxin in each of the prey animals that a secondary consumer eats, the amount of the toxin in its body will be larger because each predator eats many prey. When the secondary consumer is eaten, the higher level predator gets all of its toxins, plus those of all the other prey it eats" (Ritter, 2001, pg.54). The concentration of the toxin increases as the stages of the food chain increases.
