Use of pesticides to protect our crops affect organisms at various trophic levels especially human beings. Name the phenomenon involved and explain how does it happen.
Solution
Phenomenon – Biological Magnification /Biomagnification
Pesticides are washed down into the soil and water bodies.
From the soil pesticides are absorbed by crop plants along with water and minerals and enter the food chain.
These chemicals are non-biodegradable and get accumulated progressively at each trophic level.
As human beings occupy the top level in any food chain, the maximum concentration of these chemicals gets accumulated in our bodies.
