Saprotrophs are organisms that decompose and absorb nutrients from organic matter externally. Saprophytes, often used interchangeably, specifically refer to plants, but this term is largely outdated as most decomposers are fungi, not plants.

Key Differences
Ecological Importance: Both terms underscore the critical ecological role these organisms play in nutrient cycling. Whether called saprotrophs or saprophytes, these decomposers ensure that nutrients locked in dead organisms are returned to the environment, supporting life's continuity.

Terminological Evolution: It's essential to understand how language evolves in science. Saprotrophs is a more inclusive and accurate term, acknowledging the primary role fungi and bacteria play in decomposition. On the other hand, saprophytes, being plant-centric, doesn't capture the ecological reality accurately.

Saprotrophs: This term represents a diverse group of organisms, primarily fungi and bacteria, that play a critical role in decomposition. By secreting enzymes, saprotrophs break down complex organic matter externally and then absorb the released nutrients. The ecological role of saprotrophs is vital as they recycle organic material, making nutrients available to other organisms.

Nutritional Methods: Both saprotrophs and saprophytes are involved in the breakdown of dead and decaying organic matter. The difference lies primarily in the terminology and the organisms they traditionally referred to. Saprotrophs use enzymatic decomposition and then absorb nutrients, while "saprophytes," in outdated usage, would have indicated a plant deriving nutrition from decayed matter.

Saprophytes: Historically, this term was used to describe plants that obtained nutrients from decaying organic matter. However, as our understanding evolved, it became clear that true plants are rarely, if ever, saprophytic. Most of the organisms previously termed "saprophytes" are fungi. Hence, the term has become somewhat obsolete in modern botanical and ecological discussions.
