Ordinary fictional balcony club. A sealed display sketch shows crumbly material, a leaf piece and spaces; no living animal is shown. A source card F3 describes soils as habitats for organisms, supporting plants and regulating water. These general soil roles come from USDA NRCS, not from the sketch proving local performance. A second source card F4 describes CSIRO's Chameleon system as using soil-water information to help irrigation decisions. The club wants three short labels for a soil display: plant support, habitat, and water. Nobody has tested drinking-water safety or sampled the balcony soil.
Question
What can soil support besides holding a plant upright?
