Grad Print Calculator Periodic Table Question 7 of 11 Sapling Learning Which of the following describes the process of nitrogen fixation? O plants converting ammonia (NH3) to atmospheric nitrogen (N2) O plants converting atmospheric nitrogen (N2 o ammonia (NH3) O bacteria converting atmospheric nitrogen (Nz) to ammonia (NH3)
Solution
Ans:
Option 3. Bacteria converting atmospheric Nitrogen (N2) to ammonia (NH3).
Nitrogen fixation is conducted by a variety of bacteria, both as free-living organisms and in symbiotic association with plants.
They contain symbiotic bacteria called rhizobia within nodules in their root systems, producing nitrogencompounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants; this helps to fertilize the soil.
