Answer:
Biologists can grow specific plants to detoxify an area contaminated with heavy-metal pollution using the method of Bioremediation.
To rid an area of mosquitoes, biologists introduced a species of fish into bodies of water that feed on the mosquito larvae. This method is an example of Biological Augmentation.
Step-by-step explanation:
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.
