Bio concentration of pesticides – Bio concentration of pesticides means accumulation of pesticides in the living organisms such as animals, plants, and human beings.

Process of bio concentration of pesticides – Pesticides are poisonous chemical substance, which are sprayed over crop plants to protect them from pests or insects, that is, snall harmful insects and duseases. These chemical pesticides mix up with the soil and water. From soil and water, these pesticides are absorbed by the growing plants along with water and other minerals. When herbivorous animals eat plant as a food then these poisonous chemical pesticides go into their bodies through the food chain. Similarly, when the carnivorous ear herbivorous then these pesticides get transferred to their bodies. Human beings omnivorous eat plant food as well as herbivores. So the pesticides present in plant food and herbivores also get transferred to the body of human beings through food.

In this way, the pesticides enter the food chain at the producer level that is plant level in the process of transfer of food through trophic levels, these harmful chemicals get concentrated at each trophic level is called bio concentration of pesticides.
