Abstract: Physiological or biological stress is an organism's response to a stressor such as an environmental condition or a stimulus. Stress is a body's method of reacting to a challenge. Toxic metals are now everywhere, and affect everyone on planet earth. They have become a major cause of illness, aging and even genetic defects. Copper isessential for the function of most living organisms. But increased concentrations of copper in soils are harmful to soil organisms. Most microorganisms are known to have specific genes for resistance to stress due to heavy metals. Some of the bacteria are resistant to heavy metals and some have attained adaptation towards the toxic effects of the metals. It is also found that soils containing significant copper residues are stressful for earthworms and have been observed to have few earthworms. From the present study also, it was seen that, copper is a stressful factor for soil bacteria and earthworms and both the organisms are affected from the experimental concentrations of Copper.
