How is acetylene useful in studies of nitrogen fixation?
Answer:
Introduction: Nitrogen fixation is the phenomenon in which atmospheric nitrogen is converted by either a naturally or an industrial means to a form of nitrogen such as ammonia, nitrites, and nitrates that is used by plants.
nitrogen is abundant in the air; most organisms are not able to use it in that form. Nitrogen-fixing bacteria carried out more than 90 percent of all nitrogen fixation and therefore play an important role in the nitrogen cycle.
Nitrogen fixation process is of two types 1) Symbiotic- The symbiotic nitrogen-fixing bacteria example Rhizobium, enters the root hairs of host plants, Within the nodules of roots of plants the bacteria convert free nitrogen to ammonia, which the host plant uses for its development.
2)Non-symbiotic- the non- symbiotic nitrogen fixation is a done by free-living bacteria in the soil example the Cyanobacteria.
