Question

WHAT IS NITROGEN. FIXATION ?

MENTION ATLEAST 3-3 DIFFERENCES BETWEEN NITRIFICATION AND DENTRIFICATION. ?

ALSO NAME THE ORGANISMS INVOLVE IN THIS PROCESS

Answer 1

Answer:

Nitrogen fixation is the process through which nitrogen gas is converted into inorganic nitrogen compounds. A small amount of nitrogen gas is fixed by abiotic means such as lightning or ultraviolet radiation, which reacts with nitrogen gas in the atmosphere to produce nitric oxide.

Diff. Nitrification&Dentrificatio.

Nitrification.....

• Nitrifying bacteria like Nitrobacter, Nitrosomonas.
• Nitrifying bacteria like Nitrobacter, Nitrosomonas.Grows slowly. Requires aerobic condition
• Requires aerobic conditionProvides nitrate to the plant, which acts as the important nitrogen source.

Denitrification.....

• Denitrifying bacteria like Spirillum, Lactobacillus, Pseudomonas, Thiobacillus.
• Grows rapidly.
• Grows rapidly.Requires anaerobic condition.
• Denitrification is used in wastewater treatment and is beneficial for aquatic habitats.

Organism involve in nitrification process......

● bacteria like Nitrobacter, Nitrosomonas
