Give the two ways nitrogen can be fixated so plants can use it to grow.

Maurinko [17]

$\huge\mathfrak\red {Answer:}$

<h2>Fixation</h2>

Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:

<h3>Biologically: </h3>

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. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.

<h3>Through lightning: </h3>

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