I hope you and your family are doing good. I am writing this letter to let you know the way we celebrate independence day in Ghana. All the streets and roads are decorated with confetti. Firecrackers are being lit everywhere. The kids are getting their faces painted with Ghana's flag. My mother is also cooking a special dinner for all of us. I will send you pictures of the entire event. Thanks!
Yours truly,
XYZ.

a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
