What is the correct sequence of biomagnification due to a contaminated water body?

Biomagnification climbs the food chain, so toxins first taken up by the smallest organisms concentrate upward toward top consumers.

Bacteria absorb contaminants directly from the polluted water at the base.

Zooplankton feed on the bacteria and carry higher toxin loads.

Fish eat the zooplankton and accumulate still greater concentrations.

Humans at the top receive the most magnified dose, giving the order bacteria, zooplankton, fish, humans.

Fat-soluble, persistent pollutants like mercury and DDT magnify most strongly along such chains.
