Are subs dependent on soil contact exclusively?

The assertion that subs are dependent on soil contact exclusively is rooted in the understanding of their habitat and physiological requirements. Many subs, particularly invertebrates such as certain soil organisms, require direct contact with soil to fulfill vital functions, including respiration, feeding, and reproduction. Soil provides not only a medium for these processes but also a source of nutrients and a protective environment against predators and desiccation.

While there are exceptions and variations in dependency based on specific organisms or environmental factors, the principle holds that for many species, especially those that are adapted to a terrestrial ecosystem, soil contact is essential for survival. For instance, earthworms thrive in contact with the soil as they extract nutrients and aerate the substrate, highlighting the critical role that soil plays in their life cycle.

In these contexts, the idea that subs are exclusively dependent on soil contact underscores the importance of soil health and preservation for the broader ecosystem, as these organisms are integral to processes like nutrient cycling and soil formation.
