What phenomenon occurs when lipid-soluble persistent toxic chemicals like PCB increase in concentration in organisms at higher trophic levels?
Answer and explanation
Correct answer: C. Biomagnification
- Step 1: Fat-soluble compounds resist degradation and accumulate in animal tissues. Step 2. As consumers ingest lower-trophic organisms, concentration multiplies at each successive step, termed biomagnification. Answer: Biomagnification. Why not the others: Eutrophication is nutrient overloading in water bodies; bioerosion is biological breakdown of substrate; denitrification converts nitrate to nitrogen gas.
