Process

The process of getting worms and using them as a source of nutrients, whether by animals (in nature) or humans (in food systems or composting), involves several biological and/or ecological steps. Here's a breakdown depending on the context: # Detection: Vermivores use their senses, like smell, vibration detection, or sight, to locate worms underground or above ground. # Extraction: Vermivores will dig or peck their way to the worm or what til they come to the surface(usually at night or in the rain). Then they retrieve it. # Ingestion: The worm is consumed whole or in parts. # Digestion and Absorption: Worms are high in protein, amino acids, iron, and moisture. Vermivor’s digestive system breaks the worm down into usable nutrients, absorbed into the bloodstream for energy and growth.
