An increase in the concentration of a substance that occurs in a food chain is called
-
bioaccumulation
-
biomagnification
-
bioconcentration
-
eutrophication
B
Correct answer
Explanation
Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance that occurs in a food chain. It occurs as a consequence of:
• Persistence (can't be broken down by environmental processes)
• Food chain energetics
• Low (or nonexistent) rate of internal degradation/excretion of the substance (often due to water-insolubility)
