Answer:

Biologists can grow specific plants to detoxify an area contaminated with heavy-metal pollution using the method of <u><em> Bioremediation. </em></u>

Bioremediation can be described as a process which uses plants or microorganisms to detoxify contaminants that are present in an area. The enzymes of a plant or animal tend to break down the contaminants and hence, we can make an area rid of contaminants in this way.

Biological augmentation can be described as a method by which organisms such as bacteria are introduced in an area to get rid of wastes.
