Given that fungi are heterotrophs that feed by absorption and can digest almost any organic molecule, what is their primary ecological role as described in the text?

  • A: Primary producers, converting light energy into organic compounds.
  • B: Consumers, primarily ingesting other organisms for nutrients.
  • C: Decomposers, breaking down dead organic matter and recycling nutrients.
  • D: Nitrogen fixers, converting atmospheric nitrogen into usable forms for plants.

Explanation

The text explicitly states that fungi are 'highly effective decomposers in ecosystems' because they can digest almost any organic molecule, breaking down organic matter and releasing nutrients, which is the definition of a decomposer's role.
