Question

Nitrogen (N2) present in the atmosphere is directly absorbed by​

Answer 1

Answer:

Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants

Answer 2

Answer:

Nitrogen (N2) present in the atmosphere is directly absorbed by​ nitrifying bacteria.

Explanation:

• Plants directly absorb atmospheric nitrogen to create plant proteins.
• Nitrogen gas in the atmosphere is converted to ammonia by nitrogen-fixing bacteria in the soil and in the root nodules of some plants. Ammonia is converted to nitrites or nitrates by nitrifying bacteria. Plants can take up ammonia, nitrites, and nitrates, which are all forms of fixed nitrogen.
• Nitrogen cannot be taken up by plants straight from the air. Gaseous nitrogen can only be transformed into nitrites or nitrates in soil by nitrifying bacteria. Through their root hairs, plants can take up nitrate or nitrite from the soil.
• Nitrogen must first be transformed by nitrifying bacteria before it can be taken and used as a nutrient by plants and animals and become part of food chains.

Thus this is the answer.
