Which of the following is an example of biomagnification in a food chain?
Rising concentration of DDT from water to algae to fish to birds
Biomagnification refers to the increasing concentration of a substance like DDT as it moves up the food chain, from water to algae to fish to birds.
Algal blooms from nitrates, pesticide evaporation, and silt sedimentation describe other environmental processes, not the buildup of a toxin through a food chain.
Hence, 'Rising concentration of DDT from water to algae to fish to birds' is the correct answer.
