categories that correspond and structure the functions of soil bacterial communities.

Interaction with other organisms

Copiotrophic relation between oligotrophic bacteria depends on the amount of concentration the soil has of C compounds. If the soil has large amounts of organic C, it would then favor the copiotrophic bacteria.

Ecology
