Question

what is biological magnification

Answer 1

Heyaa folk,

♣ Biological Magnification :

The process in which certain substances like pesticides and heavy metals move up the food chain, work their into water bodies, and get eaten by aquatic animals and organisms. This is called Biological Magnification.

We can simply say, increase in toxic chemicals in tissues of living organisms is called Biological Magnification. It occurs in higher levels of food-chains.

The effect of this may include the building-up of the harmful substances inside living organism's cells. Toxic substances can enter in tropic levels by this process.

Hope it helps u :)

Answer 2

    The man-made wrongful process of harmful chemical substances and heavy metals getting mixed in big river bodies (lakes, rivers, canals and seas) and then move into the food chains of the ecosystems is called biological magnification. The result is that they get into the diet of aquatic organisms. Then these get into the bodies of higher level predators in the food chain.

 

    Because of mixing of toxic chemical substances in water and Earth, the animals, birds, fish and humans who feed on these get infected. Their bodies build gradually materials harmful to their own health.

 

Reduce the effect of biomagnification or biological magnification by

1. preventing oily wastes from cooking, oil, grease, chemicals, dyes, wasted pills, medications, used sanitary napkins, cleaning agents, pesticides, herbicides, fertilizers  into the sewerage or drainage through sink in the kitchen or flushing through toilets.

2. Dispose of the garbage properly through the municipal disposal system.

3. Organic farming reduces the use of pesticides, herbicides and fertilizers.
