The eruption of Mount Saint Helens has proved to have dramatically change the abiotic and biotic factors of its environment. As what was shown in the image just 24 years from its eruption, we can already observe that animal life began to populate the region due to its sufficient vegetation.
Answer:
Denitrifcation
Explanation:
<em>Thiobacillus dentrificans</em> is the gram-negative bacteria that is considered the chemoautotrophic according to its mode of nutrition.
The <em>Thiobacillus</em> is now used by the bioremediation scientists in the remediation of the wasteland as its ability to convert the reduces nitrogen forms that are nitrates and nitrites back to its dinitrogen state which escapes back into the atmosphere thus completing the nitrogen cycle.
This process of conversion is known as the denitrification and on the basis of this, the bacteria are named dentrificans.
Thus, denitrification is the correct answer.
