Question

what is biological magnification ?will the level of this magnification be different at different levels of the ecosystem?

Answer 1

$\underline\bold\pink{\huge{HELLO\:DEAR}}$

⚡️ BIOLOGICAL MAGNIFICATION (OR BIO-MAGNIFICATION) MEANS INCREASING OF THE CONCENTRATION OF VARIOUS TOXIC SUBSTANCES ALONG THE TROPHIC LEVELS.

⚡️ THE PHENOMENON OF CONCENTRATED TOXIC DEPOSITION AT HIGHER TROPIC LEVEL IS KNOWN AS BIO-ACCUMULATION.

⚡️ YES, IT IS DIFFERENT AT DIFFERENT LEVELS OF THE ECOSYSTEM. AN EXAMPLE OF THE PHENOMENON OF BIO-MAGNIFICATION WAS FIRST NOTICED IN ILLINOI (USA) WHERE ELM TREES WERE SPRAYED WITH DDT.

$\textbf{BIOLOGICAL MAGNIFICATION}$

When harmful chemicals enter in the food chain and gets concentrated at each tropic level then it is known as Biological Magnification.

OR

The increase in concentration of harmful substances in the body of the living organism at each tropic level is known as Biological Magnification.

$\textbf{Yes,}$

The levels of Biological Magnification different at different levels of the ecosystem. It will be maximize at highest tropic levels and minimum at lowest tropic levels.
