Question

what is meant by biological magnification

Answer 1

    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.

 

    The increase in toxic materials in the organisms higher up in the food chain, due to their presence in the organisms in the lower levels is called biological magnification.

 

    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.

 

Answer 2

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.

We can reduce it by using organic fertilizers. As Well as we can avoid it by disposing garbage. And by managing kitchen wastes. By some various more processes we can avoid biological magnification.

Hope it helps u :)
