Explain how harmful chemicals enter our body. Write the name given to such a phenomenon.

(N/A) Harmful chemicals enter our bodies through the food chain. When these chemicals are sprayed in agricultural fields,they are often non-biodegradable,meaning they persist in the environment and may wash into water bodies. When human beings consume agricultural products or aquatic organisms such as fish or prawns,these chemicals are transferred and accumulate in their bodies at higher concentrations.
This phenomenon is called 'biological magnification' or 'biomagnification'.
