Answer 1

Answer:

___________________________________

Explanation:

Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, 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 – mainly due to water-insolubility
