What type of organisms are saprophytes?

Saprophytes are organisms that obtain their nutrients by decomposing dead organic matter. This process is essential for nutrient recycling within ecosystems. Fungi, which include molds and mushrooms, are prime examples of saprophytes. Specifically, they break down complex organic materials, such as dead wood, leaf litter, and other organic debris, returning valuable nutrients to the soil and promoting the health of the ecosystem.

The other choices do not fit the definition of saprophytes. For instance, plants that produce their own food through photosynthesis are classified as autotrophs, not saprophytes. Insects that feed on living plants are herbivores, which consume living tissue rather than decomposing material. Similarly, microorganisms that cause diseases fall into the category of pathogens, which can harm living organisms rather than breaking down dead matter. Thus, the clear association of fungi with the decomposing role in the ecosystem confirms the accuracy of identifying them as saprophytes.
