Question

Quizplus · Accepted Answer

Bioremediation involves the use of living organisms to break down or remove pollutants from the environment. Adding seeds of a chromium-accumulating plant to soil contaminated with chromium would be an example of bioremediation as these plants have the ability to absorb and accumulate high levels of chromium, thereby reducing its concentration in the soil. Options A, B, and C do not involve the use of living organisms for remediation.
