Explain Biological Magnification.
Answers
ANSWER :
The increase in the concentration of harmful chemicals such as chemical fertilizers and pesticides in the living organisms at each trophic level along a food chain is called as Biological Magnification.
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
