An organism that feeds directly on primary producers, typically herbivores that eat plants, algae, or other autotrophs. They occupy the second trophic level in food chains and convert plant biomass into animal biomass.
From Latin 'primarius' (first) and 'consumer' from Latin 'consumere' (to use up completely). The term emerged in ecological studies to classify organisms by their feeding relationships.
Primary consumers face a unique challenge - they must extract nutrients from some of the most difficult-to-digest materials on Earth! Many have evolved complex digestive systems with multiple stomach chambers or rely on symbiotic bacteria to break down cellulose.
