Notes:
Biological magnification is the increase in concentration of certain fat-soluble chemicals in successively higher trophic levels of a food chain or food web. In other words, as chemical compounds move up through the various links of a food chain by being consumed by different organisms, the toxic effect of these compounds is magnified. It plays a devastating role in certain types of pollution.
48. An organism which can monitor air pollution is ____:
[A] Bacteria
[B] Lichen
[C] Algae
