anisms and microenvironment
Metabolically related populations constitute groupings called guilds.
Sets of guilds plementary physiological processes interact to form munities.
In a microbial ecosystem individual cells grow to form populations.
munities then interact munities of anisms to define the entire ecosystem.

The distribution of anisms in nature ecosystem depends on the resources (nutrients) available and on the growth conditions.
Temperature, pH, water availability, light, oxygen of a habitat define the niche for each particular anism.
A soil posed of mineral ponents, showing that localization of soil microbes. Very few anisms are found free in the soil solution; most of them occur as microcolonies attached to the soil particles.
