How does a pollutant travel through a food chain?

Anwser today ill pick the best one in about 3 hrs

the pollutant is first eaten by first organism and then that organism is eaten by other . So the pollutant travels.\ through organism in a food chain>

Pollutants in the Food Chain
i.Bioaccumulation: process by which cells selectively absorb and store a great variety of molecules, thus allowing the cell to accumulate nutrients and essential minerals, but they also absorb and store harmful pollutants.
1.Bioaccumulation increases the concentration of a pollutant from the environment to the first organism in a food chain
ii.Biomagnification: process by which the effects of pollutants are magnified in the environment through food chains.
1.Because some pollutants are very stable and resist metabolic degradation, they can remain for a long time inside organisms.
2.When an organism is consumed by a member of a higher trophic level, the consumer is only able to assimilate roughly 10% of the biomass of the prey.However, because its solubility and stability, much of the pollutant is passed on from prey to consumer.
3.Therefore, as the pollutant moves up the food chain the concentration of the pollutant in the body tissue increases dramatically.

When Plant eaters eat polluted plants

get eaten by meat eaters and then these meet eaters get eaten by other meat eaters.

all of the above could breathe or drink pollutants also.

Biomagnification.

Basically a contaminant will enter the body of an animal. Some contaninants are not able to be filtered out by the body and they stay in the animals for it's entire lifetime. That animal is eaten by another animal. The predator eats lots of animals that have the contanimant and they build it up in higher amounts.
As you most up the food chain, I've read that that contanimant levels of the animals can increase as much as ten times from one trophic level to he next.
