Question

how bacteria fix nitrogen?

Answer 1

hey friend your answer.

They contain symbiotic bacteria called rhizobia within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, thefixed nitrogen is released, making it available to other plants; this helps to fertilize the soil.

Answer 2

Answer:

The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development.
