Question

5 Give two ways of Nitrogen fixation in plants. .​

Answer 1

Answer:

Biologically: Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants.

Through lightning: Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.

Answer 2

Answer:

Nitrogen fixation is the process which takes place in nature.

This process involves the conversion of Nitrogen (N 2 ) into ammonia (NH 3 ).

There are two methods that change atmospheric nitrogen into usable forms through the process of nitrogen fixation:

[1]. H igh temperature and pressure in the air convert atmospheric nitrogen into oxides of nitrogen during lightning and thunder that can dissolve in water to produce nitric and nitrous acids. These fall along with rain.

[2]. Some forms of bacteria can convert atmospheric nitrogen into usable forms such as nitrates and nitrites. Such nitrogen fixing bacteria are commonly found in the roots of leguminous plants.

These usable forms of nitrogen are absorbed by plants to produce many compounds such as amino acids, which in turn form proteins.
