Food Chain: A sequence that links species by their feeding relationships. Herbivores: Organisms that only eat plants. Carnivores: Organisms that only eat animals. Omnivores: Organisms that eat both plants and animals. Detritivores: Organisms that eat detritus‚ or dead organic matter. Specialist: A consumer that primary eats one specific organism. Generalist: Consumer that has varying diet. Trophic levels: The levels of nourishment in a food chain. Food Web: Shows the network of feeding relationships
