Vedclass · Answer

(B) Biomagnification refers to the increase in concentration of non-biodegradable pollutants (like $DDT$) at successive trophic levels in a food chain.According to the $NCERT$ textbook data for aquatic food chains,the concentration of $DDT$ increases from $0.003\, ppm$ in water to $0.04\, ppm$ in zooplankton.It further increases to $0.5\, ppm$ in small fish,$2\, ppm$ in large fish,and up to $25\, ppm$ in fish-eating birds.Therefore,the concentration in small fish is $0.5\, ppm$.

If the concentration of $DDT$ in water is $0.003\, ppm$,what could be its concentration in small fish due to biomagnification (in $, ppm$)?
