1. 
   Biomagnification
   The increase in concentration of a persistent pollutant along a food chain e.g. persistent organochloride insecticides and their metabolites accumulating up a food chain.

2. 
   Biomagnification
   The accumulation of a substance by an animal that preys on other animals that have themselves accumulated the substance. This process can deliver remarkably high concentrations of persistent chemicals or heavy metals to top predators even if the levels in the surrounding physical environment are quite low.

3. 
   Biomagnification
   This term denotes the accumulation of substances in a living organism from food intake. Simple organisms such as algae can absorb minute quantities of a substance which are transferred through the food chain to higher levels such as fish and preditory birds. Biomagnification along a food chain will result in the highest concentrations of a substanc...

4. 
   biomagnification
   ecological magnification Sequence of processes in an ecosystem by which higher concentrations are attained in organisms at higher trophic levels (at higher levels in the food web); at its simplest, a process leading to a higher concentration of a substance in an organism than in its food.

5. 
   Biomagnification
   This is a general term applied to the sequence of processes in an ecosystem by which higher concentrations are attained in organisms of higher trophic level, i.e., of higher levels in the food chain. The process by which xenobiotics increase in body concentration in organisms through a series of prey-predator relationships from primary producers to...

7. 
   Biomagnification
   The increasing concentration of a compound in the tissues of organisms as the compound passes along a food chain, resulting from the accumulation of the compound at each trophic level prior to its consumption by organisms at the next trophic level.

8. 
   Biomagnification
   `Biomagnification`, also known as `bioamplification`, or `biological magnification` is the increase in concentration of a substance, such as the pesticide DDT, that occurs in a food chain as a consequence of: * Food chain energetics * Low (or nonexistent) rate of excretion/degradation of the substance. Although sometimes used interchangeably with 'bioaccumulation,' an important distinction is drawn between the two. *`Bioaccumulation` occurs `wi...

9. 
   biomagnification
   bioamplification, biomagnification The increase in concentration of a pollutant from one trophic level in a food chain to another; this usually occurs when the pollutant is metabolized and excreted much more slowly than the nutrients that are passed from one trophic level to the next. Such pollutants are long-lived, mobile, soluble in fats, and biologically active. Biomagnificat...
