Study Notes
Holozoic Nutrition
- Characterized by the ingestion and internal digestion of complex organic substances, such as other organisms or organic matter
- Exhibited by animals, including protists, such as protozoa and some metazoa
Energy Acquisition
- In holozoic nutrition, animals obtain energy by breaking down and utilizing the organic molecules from ingested substances
Contrasting Nutrition
- Contrasts with autotrophic nutrition, where organisms produce their own energy through photosynthesis or chemosynthesis
Mode of Nutrition
- In holozoic nutrition, animals exhibit heterotrophic nutrition, meaning they rely on external sources of energy and organic compounds
