(a) The number of aerobic micro-organisms present per gramme of the soil.

(c) The number of aerobic organisms "growing at 37° C." present per gramme of the soil.

Gradually, as decay progresses, the aerobic organisms increase in number.

Anaerobic species usually require little oxygen, but aerobic species a free supply.
