Define biological magnification?
Answers
The accumulation or increasing of toxic and chemical substances from one tropic level to another tropic level is called biological magnification.
The way by which the chemical substances enters the food chain is that when the farmers add chemical fertilisers , pesticides ,insecticides ,etc. to his for increasing fertility and for the good production of crops .
When the farmer do this the chemical substances added to crops and when human beings and various herbivores eat the crops these chemical substances entered into their body . As we that the chemicals are non biodegradable so they continuously accumulated in their body .
When these animals eaten by the decomposers the all accumulated chemicals entered into them , which causes the death of decomposers.
Biological magnification is continuously increasing and because of which the lifespan of herbivores became short and this is the only reason for the declining of decomposers as the chemicals are are added in large quantity by farmers.
