nematodes

include threadworms and eelworms, 20-100 um long

protozoa

less than 200 um long

archaea

a domain of organisms that has previously been classified as bacteria

bacteria

structurally simple but functionally complex, may pack up to 1,000 enzymes

cyanobacteria

a phylum of bacteria that obtains energy through photosynthesis and fix atmospheric nitrogen

actinomycetes

like bacteria because they are prokaryotic and their walls are like that of bacteria, also known as thread bacteria

fungi

no chlorophyll, exists in a wide range of soil pH but dominate at low pH due to reduced competition

mycorrhizae

‘Fungus-Roots’, utilizes carbon from the plant while benefitting the plants by increasing uptake of phosphorus and water

lichen

‘Fungus-Algae’, provides growth factors to the algae while the algae provides photosynthesis

algae

have chlorophyll and are photoautotrophs, live near the soil surface
