Answer:
1. Bioremediation
2. Biological Control
Explanation:
Bioremediation is the process in which the environmental condition of the contaminated media such as land, water and soil is altered with the growth of microorganisms and plants to treat the contamination.
So, biologist used the method of bioremediation, by using specific plants that will detoxify the area contaminated with heavy-metal pollution.
Biological control is the method in which pests such as mites, weeds, insects and plant diseases are controlled by using other organisms.
So, here also biologist used biological control method and introduced species of fish into bodies of water to control mosquitoes development.
Hence, the correct options for the blanks are 1. Bioremediation and 2 . Biological Control.
