Which of the following describes an organism that feeds on dead or decaying organic matter?

An organism that feeds on dead or decaying organic matter is known as a saprophyte. This term specifically refers to those organisms, including certain fungi and bacteria, that play a crucial role in the decomposition process by breaking down complex organic materials. This process recycles nutrients back into the ecosystem, which is essential for the health of the environment.

In contrast, predators are organisms that hunt and consume live prey, while herbivores primarily feed on living plant material. Consumers is a broader term that encompasses various feeding strategies, including herbivores, carnivores (predators), and omnivores, but it does not specifically refer to the act of decomposing dead matter. Therefore, saprophytes are distinct in their role as decomposers in the food web, making this answer the most accurate.
