Question

Explain biological magnification with help of an example

the process of increase of concentration of harmful chemicals like pesticides of concentration from first trophic level to the last trophic level in a food chain is called biological magnification.  

In the food chain,  

Grass ----> Grasshopper ----> Frog ----> Snake ---->Peacock  

Since peacock occurs at the highest trophic level (on the extreme right), therefore, peacock will have the maximum concentration of harmful chemicals in its body.

Biological Magnification➫ The process by which the harmful & toxic substances the tissues of organisms at higher levels in a food chain.

❱ It is also known as Bioamplification.

❱ It occurs when pollutants taken up by organisms at the base of the food chain reach high concentrations in the bodies of animals at the top of the food chain.

➧ Harmful Effects are:-

=======================

❱ 0rganisms at the top of the food chain are at a greater risk of damage due to biomagnification.

❱ It tend to have a higher risk of developing certain:-

♦ Cancers

♦ Liver failure

♦ Birth defects

♦ Brain damage

♦ heart disease

❱ The toxins responsible for these health problems include:-

♦ Mercury
