• Describe how some toxins can bioaccumulate. Your
  answer must include the words, food pyramid (or
  food web), producers, primary consumers,
  secondary consumers, tertiary consumers.

4
Answer

• Bioaccumulation occurs when toxins are stored in
  the bodies of producers. There may be only a
  small amount of toxin per individual producer but
  many producers are eaten by primary consumers.
  Then many primary consumers are eaten by the
  secondary consumers. Then many secondary
  consumers are eaten by the tertiary consumers.
  The concentration of toxin in each level of the
  food pyramid increases because the toxin is
  passed from one level to the next. It is as if
  the tertiary consumer eats a great many producers
  and gets all of the toxin from all of those
  producers.
