Pls answer the following

Dear Student, (i) The phenomenon given here is Biomagnification. It refers to the building up of substances (generally toxins) from lower trophic level to higher trophic level. It mainly affects the tertiary level organisms because we consider that at each trophic level, there is 10% increase in concentration of a given toxin. In the given food chain (Aquatic Plants---> Fish---> Eagle) there are two trophic levels and so there is nearly 20% increase in concentration when it reaches eagle and so it has affected the same. (ii) Ozone Layer protects mankind and other living organisms from Harmful ultraviolet Radiation (UV Radiation) from sun. Depletion of ozone layer can cause these radiations to reach to earth. This is the main reason for increased incidence of skin cancer in world. It may also cause mutations in living organisms and change the genetic makeup of the organism. That's why depletion to ozone layer is cause of concern. For the next question please send the image properly. Regards
