If silver nanoparticles are ingested by zooplankton at the base of a freshwater food web, which consequence affecting higher trophic levels is most likely?

A)Increased primary production rates
B)Enhanced nutrient cycling efficiency
C)Population boom in all fish species
D)Biomagnification of silver concentrations

💡 Explanation

Biomagnification will occur, because non-degradable substances like silver nanoparticles become increasingly concentrated in organisms at higher trophic levels as they consume contaminated prey; therefore, top predators will have the highest silver concentrations, rather than a reduction in primary production.
