Last questions!!

Soil organisms:

Carla, you should know the major groups (as per the class notes and text) as you indicate above, but within fungi and bacteria, as they include a wide range of organisms with different functions it would be useful to know important subgroups e.g. heterotrophic bacteria, nitrifying bacteria (your examples of nitrobacter and nitrosomas), N-fixing bacteria (your example of rhizobium with legumes), cyano-bacteria; similarly for fungi - heterotrophic fungi (decomposers), and mycorrhyzal fungi.

Thank you
