What advantages are there to digestion Would it not be simpler for a vertebrate to simply absorb carbohydrates lipids and proteins from its food and to use these molecules without breaking them down?

Digestion allows vertebrates to break down complex macromolecules into smaller, absorbable units, such as amino acids, simple sugars, and fatty acids, which are necessary for efficient nutrient absorption and utilization. This process also enables the body to regulate the release of nutrients and manage energy levels more effectively. Additionally, digestion helps in detoxifying harmful substances and pathogens present in food. Simply absorbing intact macromolecules could lead to inefficiencies and potential health risks due to the body's inability to handle large structures.
