Explanation:
DDT (Dichlorodiphenyltrichloroethane) is an organochlorine chemical commonly used as an insecticide. It was widely used in the mid-20th century to control mosquito populations and agricultural pests, but its use was banned in several countries due to its harmful effects on the environment.
Biomagnification is a process in which the concentration of a substance increases as it moves up the food chain. DDT is known to cause biomagnification because it is liposoluble.
Liposolubility refers to a substance's ability to dissolve in fat. DDT is highly liposoluble, which means that it can easily dissolve in fatty tissues and accumulate in the bodies of animals that consume it. When a predator eats a prey that has DDT residues in its body, the predator ingests not only the DDT residues in the prey's body but also those that the prey has accumulated from its previous meals. This process is repeated as predators consume other predators, resulting in a higher concentration of DDT residues in the bodies of animals at higher levels of the food chain.
In contrast, water-soluble substances dissolve in water and are easily excreted from the body. Therefore, water-soluble substances are less likely to accumulate in the bodies of animals and cause biomagnification.
In conclusion, DDT residues are rapidly passed through the food chain causing biomagnification because DDT is liposoluble and easily accumulates in the bodies of animals, leading to a higher concentration of DDT residues in animals at higher levels of the food chain.

They are fat soluble they get incorporated in food chain and deposit in fatty tissues of animals and humans they are persistent and lipid soluble
