Meaning and Definition
The process by which the concentration of a substance (e.g., a toxin or pollutant) increases at each successive level in a food chain.
The progressive accumulation of persistent substances in the tissues of living organisms, typically from ingestion of contaminated food, leading to higher concentrations in predators at the top of the food chain.

FAQ
Frequently Asked Questions
Bioaccumulation refers to the increase in concentration of a substance in a single organism over time. Biomagnification is a specific type of bioaccumulation where the concentration increases as you move up a food chain from prey to predator.
Almost exclusively, yes. The term inherently carries a negative connotation as it describes a process that leads to potentially harmful concentrations of persistent, often man-made, pollutants or heavy metals in organisms.
Typically no. Essential nutrients like vitamins or minerals are regulated and metabolized by organisms and do not show the progressive, unchecked increase up the food chain that defines biomagnification for persistent toxins.
The standard noun is 'biomagnification'. The process is called biomagnification.
