Question

In which type of nutrition, digestion of food occurs outside the body?

• A. Parasitic nutrition
• B. Symbiotic nutrition
• C. Saprotrophic
• D. Autotrophic

Answer 1

Answer: (C)

Saprotrophic

• The plants which exhibit saprotrophic mode of nutrition are called as saprotrophs. Saprotrophs are the plants that obtain their nutrition from dead and decaying organic matter. Saprotrophs secrete digestive juices onto dead and decaying matter to dissolve it and then absorb nutrients from it.
  
• Enzymes are secreted onto the dead organism to digest the large molecules so digestion is external.
  
• So, the correct answer is 'Saprotropic'.
