Answer:

Pesticides are chemical or biological agents that are able to restrict the growth of pests in a agricultural field. These pesticides prevents the growth of insects or pests whose life cycle is mainly dependent on plants and those which are dependent for food requirement on plants. The pesticides making crop pest resistance can be harmful to animals and humans as these are toxic in nature. These pesticides can contaminate the air, water and soil in the regions where they are applied and causes respiratory, cardiac and water borne diseases in humans. These pesticides being toxic remains undigested and circulated in a food chain can be responsible for biomagnification. Biomagnification affects the growth and abundance of species in all trophic levels of the food chain but the highest trophic level is most affected because of accumulation of pesticides in the organisms reaches at higher concentration, responsible for mortality.
