On the USDA-NRCS Soil Biology Primer main paige it says that the “text, graphs, tables, non-credited photos, and graphics from USDA sources may be used freely” as long as the Soil Biology Primer or “this website” is credited. From the image captions on the Soil Food Web subpage it becomes clear that the food web diagram is a non-credited graphic.
