उत्तर
The peacock will have the highest quantity of dangerous chemicals in its body since the accumulation of non-biodegradable toxic chemicals grows at each trophic level. Bio-magnification refers to the occurrence of an increase in the concentration of hazardous substances at each trophic level. Because peacocks are at the top of the food chain, they have the highest concentration of toxic substances in their bodies. The process by which a hazardous substance enters the food chain and becomes intensified at each trophic level is known as biological magnification.
