During nitrification, which bacteria convert ammonia to nitrites?a)Nitrobacterb)Nitrosomonasc)Pseudomonasd)MycobacteriumCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

The nitrification process requires the mediation of two distinct groups: bacteria that convert ammonia to nitrites (Nitrosomonas, Nitrosospira,Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates (Nitrobacter,Nitrospina, and Nitrococcus).

Answer

Answer

Nitrification is the process by which ammonia (NH3) and ammonium ions (NH4+) are converted into nitrites (NO2-) and nitrates (NO3-) by different groups of bacteria. Nitrification occurs in two steps, each carried out by a different group of bacteria.

Step 1: Conversion of ammonia to nitrites
The first step of nitrification is the conversion of ammonia to nitrites. This process is carried out by bacteria called Nitrosomonas. These bacteria are chemolithotrophs, which means they obtain energy by oxidizing inorganic molecules. In the case of Nitrosomonas, they use ammonia as their energy source and convert it into nitrites through the following reaction:

NH3 + O2 → NO2- + H2O + 2H+

This reaction releases energy that the bacteria use to grow and reproduce. Nitrosomonas are found in soil and water environments, and they play a crucial role in the nitrogen cycle by converting ammonia to nitrites.

Step 2: Conversion of nitrites to nitrates
The second step of nitrification is the conversion of nitrites to nitrates. This process is carried out by bacteria called Nitrobacter. Similar to Nitrosomonas, Nitrobacter are also chemolithotrophs that use inorganic molecules as their energy source. In the case of Nitrobacter, they use nitrites as their energy source and convert them into nitrates through the following reaction:

NO2- + O2 → NO3-

This reaction also releases energy that the bacteria use to grow and reproduce. Nitrobacter are also found in soil and water environments, and they play a crucial role in the nitrogen cycle by converting nitrites to nitrates.

In conclusion, during nitrification, Nitrosomonas bacteria convert ammonia to nitrites, while Nitrobacter bacteria convert nitrites to nitrates.

Answer

Actually nitrosomonas converts ammonia to nitrite NO2,  but nitrobacter converts into nitrate which is asked in the question. so, answer is A.

Answer

Ans-(b) nitrosomonas

Answer

B)nitrosomonas

Answer

Yes nitrobacter ,nitrosomonas converts ammonia to nitrite and nitrobacter converts nitrite to nitrate .these bacteria utilize energy by this oxidation process

Answer

Because nitrites is toxic and so nitrobacter converts nitrites to nitrates

Answer

Answer is a

Answer

Nitrobacter converts nitrite to nitrate, not ammonia.
