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 in which the concentration of a substance increases as it passes up the food chain.

When levels of substances build up and become concentrated as they work their way up the food chain.

the accumulation/magnification of a substance as it moves through the food chain.

When the concentration of a compound is higher in a predator than in its prey, the compound is said to biomagnify. This process is important for many bioaccumulative pollutants, and causes them to concentrate at high levels in top predators.

A 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 (Dustman & Stickel, 1969).

This term denotes the accumulation of substances in a living organism with the food intake. Simple organisms such as algae can absorb minute quantities of a substance which are transferred through the [..]

The accumulation of a chemical in the tissues of an organism as a result of food web transfer.

Increasing concentrations of a chemical with higher trophic levels.

This is a general term applied to the sequence of processes in an ecosystem

Refers to the process whereby certain substances such as pesticides or heavy metals move up the food chain, work their way into rivers or lakes, and are eaten by aquatic organisms such as fish, which [..]

the accumulation of pollutants at successive levels of the food chain

the increased concentration of fat-soluble and stable pollutants in the upper parts of a food chain

 the existence of a substance at successively higher concentrations with increasing trophic levels in ecosystem food chains. cf. bioconcentration biomass:

(biology) The process, in an ecosystem, in which a higher concentration of a substance in an organism is obtained higher up the food chain.

See bioaccumulation.
