Organisms that ingest whole material typically have specialized digestive systems that break down the food internally through processes like mechanical digestion and enzymatic degradation, allowing nutrients to be absorbed and utilized.
How do organisms that take in whole material and break it down inside their bodies obtain nutrition?

Organisms that ingest whole material and break it down inside their bodies obtain nutrition through extracellular digestion followed by intracellular absorption. In these organisms, like animals, the digestive system processes complex food into simpler molecules in specialized organs such as the stomach or intestines. Enzymes are secreted to break down large molecules, and the resulting nutrients, such as amino acids, fatty acids, and sugars, are absorbed across the gut lining into the bloodstream. Subsequently, these nutrients are transported to cells where intracellular processes, including cellular respiration, enable the release of energy for the organism’s metabolism and growth.
Organisms that ingest whole material and break it down inside their bodies obtain nutrition through a process called digestion. During digestion, complex molecules in food are broken down into simpler forms that can be absorbed by the organism’s cells. This breakdown is achieved through mechanical processes like chewing and muscular contractions of the digestive tract, as well as chemical processes involving enzymes secreted by various digestive organs. Once the food is broken down into smaller molecules, such as simple sugars, amino acids, and fatty acids, these nutrients are absorbed across the lining of the digestive tract and transported to cells throughout the organism’s body. There, these nutrients are utilized for energy production, growth, repair, and various metabolic processes essential for the organism’s survival and well-being.
