Study Notes
Holozoic Nutrition
- Characterized by the internalization and digestion of solid organic matter, such as plants and animals, to obtain energy and organic building blocks
- Exhibited by animals, including humans
Energy and Organic Building Blocks
- Obtained by animals through the process of ingestion, where food is taken into the body
- Food is then digested, breaking down complex organic molecules into simpler compounds
- Energy is released from the broken-down molecules and used by the animal
Contrasting Nutrition Type
- Contrasts with saprotrophic nutrition, which involves the external digestion of dead organic matter
- Also contrasts with osmotrophic nutrition, which involves the absorption of dissolved nutrients
Other Nutrition Type
- Phagocytic nutrition involves the internalization and digestion of blood and decaying organic matter
