Thiobacillus denitrificans is a species of bacteria that obtains its energy from carbon dioxide and inorganic compounds such as
tensa zangetsu [6.8K]

Answer:

The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.

Explanation:

Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.

The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.

Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.

ira [324]

The Grand Canyon of Arizona is one of world’s largest and steepest canyons. It ranges up to 277 miles long and 18 miles wide. Its formation is carved due to the erosive power of the water’s current.  As heavy rains continue to occur, more rocks and stones erode and fall which adds length and width to the Grand Canyon.
