Question

How to calculte how much ppm will be in next tropic level in biological magnification?

Answer 1

✴Write an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L)

✴Extract the data from the question: mass solute (NaCl) = 0.0045 g. ...

✴Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g × 1000 mg/g = 4.5 mg.

Answer 2

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
