In nitrogen fixation
A. Plants convert atmospheric nitrogen to nitrates
B. Plants absorb ammonia from the soil
C. The bacteria are all housed on the plant roots
D. The enzyme nitrogenase produces ammonia from gaseous nitrogen
Answer: Option A
Solution(By Examveda Team)
In nitrogen fixation plants convert atmospheric nitrogen to nitrates.Nitrogen fixation is any natural or industrial process that causes free nitrogen (N2), which is a relatively inert gas plentiful in air, to combine chemically with other elements to form more-reactive nitrogen compounds such as ammonia, nitrates, or nitrites.
Nitrogen-fixing plants are those whose roots are colonized by certain bacteria that extract nitrogen from the air and convert or “fix” it into a form required for their growth.
