Human beings seek to build dams because because dams acts as water reservoirs. They are useful in releasing water in a controlled way, thus floods can be avoided.

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.
