Question

Biologists can grow specific plants to detoxify an area contaminated with heavy-metal pollution using the method of _________. 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 _________.

First Blank:
1) Bioremediation
2) Biological Augmentation
3) Reforestation

Second Blank:
1) Species Conservation
2) Biological Augmentation
3) Wildlife Corridors

Answer 1

The first answer is  1. Bioremediation. Biologists can grow specific plants to detoxify an area contaminated with heavy-metal pollution using the method of  Bioremediation. Heavy metals cannot be degraded during bioremediation but it can be transformed from one oxidation state to another. Due to the change in their oxidation state, heavy metals can be transformed to become either less toxic, easily volatilized, or more water soluble. 

The answer for Question # 2 is Biological Control. 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 Control.

Answer 2

1. Bioremediation

2.biological augmentation
