Vedclass · Answer

(A) Biomagnification refers to the increase in concentration of a toxicant at successive trophic levels. This happens because a toxic substance accumulated by an organism cannot be metabolized or excreted and is thus passed on to the next higher trophic level.In an aquatic food chain involving $DDT$,the concentrations are as follows:$1$. Water: $0.003 \;ppm$$2$. Zooplankton: $0.04 \;ppm$ $(b-4)$$3$. Small fish: $0.5 \;ppm$ $(a-3)$$4$. Large fish: $2 \;ppm$ $(d-2)$$5$. Fish-eating birds: $25 \;ppm$ $(c-1)$Therefore,the correct matching is $a-3, b-4, c-1, d-2$.

Column-$I$	Column-$II$
$(a)$ Small fish	$(1) \;25 \;ppm$
$(b)$ Zooplankton	$(2) \;2 \;ppm$
$(c)$ Fish-eating birds	$(3) \;0.5 \;ppm$
$(d)$ Large fishes	$(4) \;0.04 \;ppm$

Column-$I$	Column-$II$
$(a)$ Haryana	$(1)$ Ozone hole
$(b)$ Chernobyl	$(2)$ Integrated organic farming
$(c)$ Garhwal	$(3)$ Radioactive waste leakage
$(d)$ Antarctica region	$(4)$ Chipko movement
