Living organisms affect soil formation primarily by their constraining the level of oxygen in the soil.

Question

Quizplus · Accepted Answer

Living organisms have a significant impact on soil formation through processes like decomposition, nutrient cycling, and the creation of soil structure. However, their impact on oxygen levels in soils is secondary to geological factors like parent material, climate, and topography. Oxygen levels in soils are primarily a function of soil texture, structure, and drainage.
