Bacteria
Nitrogen-fixing bacteria are primarily responsible for converting atmospheric nitrogen into a useable form, such as ammonia, that can then be utilized by plants for growth and development. These bacteria are found in the root nodules of leguminous plants, where they form a symbiotic relationship with the plant.
Nitrogen-fixing bacteria are needed to convert atmospheric nitrogen into a usable form for plants. These bacteria form symbiotic relationships with certain plants, like legumes, to provide them with a source of nitrogen for growth and development.
nitrogen and oxygen
In nitrogen fixation, two molecules are produced: ammonia (NH3) and ammonium ion (NH4+). These molecules are in a usable form for plants to uptake and utilize for growth and development.
stick it in your butt :D
They absorb nitrogen from the air. Then nitrogen-fixing bacteria convert it to a useable form.
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
Nitrogen is present in the largest amount in the atmosphere - in the gaseous form. So , it is impossible for organisms to take in nitrogen . As it is less reactive, it doesn't react in the gaseous form so it has to be converted to useable form....Rhizobium is a type of useful bacteria that helps in converting gaseous nitrogen to useable form, and then it releases it into the soil. Plants tale these and produce proteins. Animals eat plants and we eat both . This is how Rhizobium is helpful.
The most usable form of nitrogen for plants is nitrate (NO3-).
Nitrogen fixing bacteria along and on the roots of plants converts gaseous nitrogen into a form that plants can absorb.
Symbiotic is the type of relationship that plants can have with nitrogen-fixing bacteria.Specifically, the noun form of the word, symbiosis, comes from the ancient Greek words σύν ("together") and βίωσις ("living"). It designates a close, long-term relationship between two organisms. The bacteria gets exudates (sugary wastes) from the plant's roots in exchange for making nitrogen available in the soluble form in which it must be in order to pass through the roots and into the plant's network for moving nutrient-rich, watery solutions up, down and around the plant's interior parts.
Because it converts nitrogen into a form plants can use.
