A geographical area consists of organisms like snake, grasshopper, peacock, grass and frog. If pesticides are used in this area to kills insects, which of these organisms will have maximum amount of pesticides in its body. Name the phenomenon involved.

Food chain and energy transfer:

• The food chain is the chain of transfer of energy and matter as food from one organism to another.

Biomagnification:

• Biomagnification is the process of the accumulation of pesticides or toxic chemicals in different trophic levels.
• The pesticides accumulated in grass are eaten by the grasshopper.
• The frog eats grasshopper and the pesticide from the grasshopper gets transferred to the frog.
• The accumulated pesticide gets passed onto the snake from the frog and then eventually it is transferred to the peacock.
• The frogs pass to the snake, and eventually, the peacock gets all the pesticides accumulated at the trophic levels below them.
• The organism present at the highest trophic level or the top of the food chain accumulates the maximum amount of the pesticide because this is a non-degradable toxic chemical.
• Peacock will have the maximum amount of pesticide.
