(d) liposoluble
Explanation:
DDT residues are rapidly passed through food chain causing biomagnification because DDT is soluble in lipids. Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance,
such as the pesticide DDT, that occurs in a food chain as a consequence of:
- Persistence (slow to be broken down by environmental processes)
- Food chain energetics
- Low (or non-existent) rate of internal degradation/excretion of the substance (often due to water in solubility)
