How do harmful Chemicals enter the food chain ?

Expert Answer:

Harmful chemicals such as pesticides get accumulated in the soil and the water gets polluted and this, in turn, is consumed by the plants to take up nutrients. Those chemicals get accumulated in the plants and go to the next trophic level. This process is also known as biomagnification.
