What term describes the process where one organism accumulates chemical residues from another organism it consumes?

The term that best describes the process where one organism accumulates chemical residues from another organism it consumes is biomagnification. Biomagnification refers to the increase in concentration of substances, such as pesticides or heavy metals, in the tissues of organisms at each successive level of the food chain. When a predator consumes prey that has accumulated these harmful substances, the concentration of contaminants becomes higher in the predator than in the prey due to the accumulation over time and the greater energy needs of the larger organisms.

In this context, while bioaccumulation is a related concept that involves the buildup of chemicals in an organism from various sources, it does not specifically refer to the process of increasing concentration across multiple levels in a food chain. Translocation typically refers to the movement of substances within an organism or from one location to another, and extrapolation involves making predictions or estimates based on existing data. Thus, biomagnification is the accurate term to encapsulate this specific process.
