Answer:
Humus
Explanation:
The entire soil content can be divided into biotic and abiotic components; the abiotic component includes non-living soil organisms, while the biotic element includes living organisms.
In general, the abiotic component of the soil accounts for about 40-45 percent of the soil volume followed by air and water which occupy 25 percent each with 5 percent covered by living things.
The exact composition of the soil, however, may vary depending on the existing rocks in the area and the climate.
Other factors that influence soil composition include the amount of vegetation, soil compaction, and water retention capacity.
