Question

biogeochemical cycles recycle water and natural elements throughout the biosphere to ensure that organisms do not run out of these substances. thiobacillus denitrificans is a specialized species of bacteria that obtains its energy from carbon dioxide and inorganic nitrogen - containing compounds such as nitrates in its environment. it is used in the bioremediation of groundwater that contains excess nitrate. how does thiobacillus denitrificans help bioremediate groundwater?

nitrification
denitrification
nitrogen fixation
decomposition

Explanation:

Thiobacillus denitrificans uses inorganic nitrogen - containing compounds like nitrates. Denitrification is the process of converting nitrates into nitrogen gas, reducing nitrate levels in groundwater.

Answer:

B. denitrification
