Answer 2

Mercury is a heavy metal that builds up in the food chain

• Food chains are a representation of the transfer of food energy from a level of organisms to the next in ecology.
• At times, certain toxins and pesticides accumulate in the higher levels of the chain.
• This process is called biological magnification i.e. biomagnification or bioamplification since they are found in progressively higher concentration as one moves up the chain.
• Example of a heavy metal found in food chain is Mercury.
