<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.

Answer:
3- spores produced in zygosporangia
5- important in the fermentation process
Explanation:
Zygomycota is a form of fungi that are more common or found in soil or on a rotting plant or animal entity. For example "Rhizopus stolonifer" is commonly known as black bread mold.
It has several characteristics some of which are:
1. spores produced in zygosporangia
3. important in the fermentation process
