The entry of poisonous substance in food chain

The concentration of harmful chemicals increases as every next trophic level in a food chain. This phenomenon is known as biological magnification

The increase in concentration of harmful chemicals at different trophic level in a food chain.
The increasing concentration of a substance,such as toxic chemical,inthe tissues of organism at successfully higher level in a food chain.
Increase in concentration of harmful substances at every tropic level and is maximum at least tropic level

Biological magnification will be different in different trophic levels . As it will be lowest in the fir1 trophic level and highest in the second trophic level
It means accumulation of non biodegradable chemicals in the living oraganisms in a food chain.The increase in concentration of harmful chemicals in the body of living oraganisms at each trophic level of a food chain is called bio.magn.

The increasing concentration level of high toxic chemicals in higher trophic levels is called bological magnification.

The process by which the harmful and toxic substances enter the food chain and get concentrated in the body of living organisms at each successive level in food chain is called biological magnification.

Biological magnification, also known as bio-magnification refers to the increase in the concentration of toxic substances like DDT, chemicals, heavy substances etc. with each successive trophic level of the food chain. The concentration of these toxic substances is highest at the highest trophic level.

The process in which harmful chemicals enter a food chain and get accumulated progessively at each trophic level, is called biological magnification
Increasing concentration of toxic chemicals in higher trophic levels is called biological magnification

Hello everyone????
Thankxxx tripti and madhav also Maina Apka answer baad ka dekha tha …Sorry
I also answered???
Mtlb..
Concentration of non biodigreable substances in your body through different tropic level this phenomena is called biological magnification
Read book mann
Thankxxx gitika and ayush..
Ok??????
Increasing accumulation of toxic substances while going from one tropic level to another
And u??????
The increase in concentration of harmful chemical substances like pesticides in the body of living organisms at each trophic level of a food chain is called biological magnification
The increment in the concentration if DDT chemical in organism if food chain / food web

Where are you from
Heyyy
Hi upasana

It is a phenomenon of progressive increase in the concentration of toxicant at each successive trophic level. Eg. Pesticides like DDT, sprinkled on plants enter the body of human beings through the food chain.

The increase in concentration of harmful non- biodegrable chemicals at different trophic levels in food chain know as biological magnification……..

The increase in the concentration of harmful chemical substances in the body of living organism at each tropic level of a food chain is known as Biological magnification
Biological magnification often refers to the process whereby certain substances such as pesticides or heavy metals move up the food chain, work their way into rivers or lakes, and are eaten by aquatic organisms such as fish, which in turn are eaten by large birds, animals or humans.
Accumulation or increasing concentration of toxic substances or chemicals in the body of an organism..
The process of accumulation of non biodegradable chemicals progressively at each trophic level
