Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Parasitic nutrition
Concept:

Heterotrophic nutrition encompasses various methods of acquiring organic food from other organisms.

Formula:

N/A

Solution:

  • When an organism (the parasite) obtains its nutrition directly from the living tissues or fluids of another living organism (the host) of a different species, it is engaging in Parasitic nutrition.
  • This relationship inherently harms the host while benefiting the parasite.


Why other options are incorrect:

Saprophytic nutrition involves feeding on dead and decaying matter. Symbiotic (specifically mutualistic) nutrition involves a mutually beneficial exchange. Mineral nutrition refers to plants absorbing inorganic ions from soil.
