Detailed Solution
Download Solution PDFThe correct answer is Biomagnification.
- Biomagnification is the concentration of a toxin at successively higher levels in a food chain.
Key Points
- Biomagnification is the trophic enrichment of contaminants within food webs and progressive increase in chemical concentrations with increasing animal trophic status.
- Biomagnification occurs when organisms like zooplankton feed upon the contaminated phytoplankton and in turn absorb Persistent Organic Pollutants (DDT) into their own tissues at a higher concentration.
- The more contaminated phytoplankton zooplankton eats, the more will be the contamination at upper trophic levels.
