All of the following are different modes of nutrition in fungi except:

Correct answer: D. Autotrophic

  • A. Parasitic
  • B. Saprophytic
  • C. Symbiosis
  • D. Autotrophic

Explanation

The correct answer is Option D: Autotrophic. Fungi are heterotrophic organisms, meaning they obtain nutrients by absorbing them from other sources. They cannot produce their own food through photosynthesis as they lack chlorophyll. The other options are valid modes of nutrition in fungi: Parasitic fungi feed on living hosts, Saprophytic fungi decompose dead organic material, and Symbiosis involves mutually beneficial relationships with other organisms. Therefore, autotrophic is the only mode of nutrition not applicable to fungi.
