In simple words..
biological magnification refers to the process of increase in the concentration of a toxic chemical with the increasing trophic level in a food chain.
Let us take the example of lead poisoning which may affect plants because of water pollution. The level of lead would be at a particular level in plants. If a herbivore eat this plant the level of lead will be more in them because it would eat a large number of plants. Similarly, when a carnivore will eat a herbivore the level of lead would rise further because he will eat a large amount of herbivore.Hence, the level of magnification will increase as we reach at higher tropic level.

Biomagnification is the increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain.
In the food chain,
Grass ----> Grasshopper ----> Frog ----> Snake ----> Peacock
Peacock occurs at the highest trophic level (on the extreme right); therefore, it will have the maximum concentration of harmful chemicals in its body.
