How do herbivores use these complex organic molecules?

Herbivores use complex organic molecules, primarily carbohydrates, proteins, and fats found in plant material, as essential sources of energy and nutrients. Through digestion, they break down these molecules into simpler forms, such as glucose and amino acids, which are then absorbed into their bloodstream. These nutrients support various bodily functions, including growth, reproduction, and maintaining metabolic processes. Additionally, some herbivores have specialized gut microbiota that help them further digest fibrous plant materials, enhancing nutrient absorption.
