Explain the phenomena of biological magnification. how does it affect the organisms of different tropic levels, particularly the tertiary consumers??

Answer»

Biomagnification, also known as BIOAMPLIFICATION or biological magnification, is the increasing concentration of a substance, such as a toxic CHEMICAL, in the tissues of tolerant organisms at successively higher levels in a food chain. This INCREASE can occur as a result of:

Persistence – where the substance cannot be broken down by environmental processes

Food chain energetics – where the substance's concentration increases progressively as it moves up a food chain

Low or non-existent rate of INTERNAL degradation or excretion of the substance – often DUE to water-insolubility
