Nutrition - Fungi • Fungi digest food by extra-cellular digestion (การย่อยอาหาร extracellular). • Enzymes are secreted by the feeding hypha • Enzymes break food into simple soluble molecules • Soluble products are absorbed into the hypha
Nutrition - Bacteria • Bacteria also feed by extra-cellular digestion. • They excrete enzymes that break food into simple molecules. • These simple molecules are absorbed by the bacteria.
Parasites (ปรสิต) Live on or in larger organisms and feed off them. If they cause disease they are called pathogens. • Saprophytes (สิ่งมีชีวิตที่กินของเน่าเปื่อย) Consume dead matter. These bacteria are scavengers and decomposers. • Autotrophs (สิ่งมีชีวิตที่สามารถสร้างอาหารได้เอง) Self-feeders. They can make food from non-livingmaterials i.e. chemicals/ sunlight. Green and purple sulfur bacteria.
