-Nitrogen is a macronutrient in plants.
-Nitrogen-fixing bacteria in the soil convert N2 to NH3.
-Nitrogen is a component of nucleic acids, proteins, hormones, and coenzymes.
-Plant roots can only absorb nitrogen in the form of ammonium ions (NH4+) or nitrate ions (NO3−).
-Nitrogen deficiency usually causes plant leaves to turn yellow.

Respuesta :

Answer;

  • Nitrogen is a macronutrient in plants.
  • Nitrogen-fixing bacteria in the soil convert N2 to NH3.  
  • Nitrogen is a component of nucleic acids, proteins, hormones, and coenzymes.
  • Plant roots can only absorb nitrogen in the form of ammonium ions (NH4+) or nitrate ions (NO3-)

Explanation;

  • Macronutrients are elements that are taken in large amounts by the plants, they include;  nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.
  • Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia.
  • Plants absorb nitrogen from the soil both in the form of nitrate (NO3−) and ammonium (NH4+).
  • Nitrogen is an essential element to form amino acids, proteins, nucleic acids, coenzymes and chlorophyll.
