what is the role of nitrogen fixing bacteria
convert gaseous nitrogen into ammonium ions
what are examples of nitrogen-fixing bacteria
azotobacter and rhizobioum
what is the role of nitrifying bacteria
convert ammonium ions into nitrites and nitrates
why does ammonium need to be converted into nitrites and nitrates
nitrates and nitrites are high soluble and can be absorbed by roots
examples of nitrifying bacteria
nitrosomonas and nitrobacter
what is the role of denitrifying bacteria
use nitrates for respiration and return the gaseous nitrogen into the atmosphere
what is the role of saprobionts (decomp)
decompose waste and dead matter via extracellular digestion making ions available for other organisms
what is the role of saprobionts (ammonium)
converts nitrogen compounds in waste into ammonia in the soil
what is the role of mycorrhizal fungi
increase SA of root systems to help absorb water and scarce mineral ions
