\nEarthworms are well-known examples of geophages. Geophagy is the practice of eating earth or soil. Earthworms consume large quantities of soil as they burrow, digesting the organic matter and associated microorganisms within the soil matrix.
\n<\/section>\n
\n– Geophage: An organism that feeds on soil.
\n– Saprophage\/Detritivore: Feeds on dead organic matter (detritus). Earthworms are also detritivores, but their primary mode of feeding involves ingesting soil containing detritus.
\n– Coprophage: Feeds on faeces.
\n– Necrophage: Feeds on dead animals (carrion).
\n<\/section>\n
\nBy ingesting soil, earthworms play a crucial role in soil formation, aeration, drainage, and nutrient cycling. They break down organic matter, mix soil horizons, and excrete nutrient-rich casts, significantly improving soil fertility and structure.
