Animal Nutrition, Digestion, and Metabolism Explained — Essentials of Food Intake and Energy Balance | Chapter 41 of Campbell Biology
Animal Nutrition, Digestion, and Metabolism Explained — Essentials of Food Intake and Energy Balance | Chapter 41 of Campbell Biology Understanding animal nutrition is key to grasping how organisms obtain, process, and utilize food for survival, growth, and reproduction. Chapter 41 of Biology provides a comprehensive look at how animals meet their nutritional needs, process food, and regulate energy metabolism. This chapter details the four stages of food processing—ingestion, digestion, absorption, and elimination—while highlighting digestive adaptations, nutrient requirements, and the hormonal control of appetite and metabolism. Watch the podcast summary below, then continue reading for an expanded guide to digestion, essential nutrients, and the metabolic processes that sustain animal life. Introduction: The Fundamentals of Animal Nutrition All animals require chemical energy, organic building blocks, and essential nutrients—amino acids, fatty acids, vitamins, and mi...
