The concentration of pesticides like DDT INCREASES as we move up the food chain. This phenomenon is called:
ABiological magnification, with toxins concentrating in top predators
BThe 10% Law of energy transfer between trophic levels
CTrophic dilution, with toxins becoming weaker at each step
DOzone-layer depletion, with chemicals reaching the stratosphere
Answer & Solution
Correct answer: A. Biological magnification, with toxins concentrating in top predators
Biological magnification is the increasing concentration of harmful substances (DDT, mercury) as they move up the food chain. Top predators accumulate the highest concentrations.
