NEET Botany Biological Classification Questions Solved

Saprotrophs live on dead organic matter, which they utilize

(1) by phagocytosis

(2) after digestion by extracellular enzymes synthesised by them

(3) by endocytosis

(4) by pinocytosis

Audio Explanation:

(2) Saprotrophic nutrition is a process of chemoautotrophic extracellular digestion involved in the processing of dead or decayed organic matter whihc occurs in saprotrophs or heterotrophs, and is most often associated with fungi such as the Mucor or Rhizopus. The process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae.
