DDT residues are rapidly passed through food chain causing biomagnification because DDT is

Options

A. Lipo soluble
B. Moderately toxic
C. Non-toxic to aquatic animals
D. Water soluble

Answer

**Step-by-Step Solution:**

1. **Understanding DDT**: DDT (Dichloro-Diphenyl-Trichloroethane) is a synthetic pesticide that was widely used for pest control.

2. **Biomagnification Concept**: Biomagnification refers to the process where the concentration of a substance, such as a pesticide, increases in organisms at each successive level of the food chain.

3. **Properties of DDT**: DDT is characterized as a liposoluble (fat-soluble) compound. This means it dissolves in fats and oils rather than in water.

4. **Accumulation in Fatty Tissues**: Due to its liposoluble nature, DDT accumulates in the fatty tissues of organisms. When an organism consumes food that contains DDT, the pesticide is stored in its body rather than being excreted.

5. **Transfer Through the Food Chain**: As predators consume prey, the concentration of DDT increases at each trophic level. This is because the predator accumulates all the DDT stored in the bodies of the prey it consumes.

6. **Conclusion**: Therefore, DDT residues are rapidly passed through the food chain causing biomagnification primarily because DDT is liposoluble.

7. **Final Answer**: The correct option is that DDT is liposoluble.
