Answer:
Saprophytes include decomposer fungi and saprophytic bacteria. They feed on dead or decaying organic matter and do not have a specialized internal digestive system. They feed by secreting an array of enzymes such as proteases, amylases, and cellulases onto the food material outside the body, from the very tip of the structure, called the hypha.
Step-by-step explanation:
Saprophytes are organisms that obtain nutrients by decomposing dead or decaying organic matter. Decomposer fungi, such as molds, and saprophytic bacteria are examples of saprophytes. Unlike organisms with internal digestive systems, saprophytes release digestive enzymes into their surroundings. These enzymes, including proteases for proteins, amylases for carbohydrates, and cellulases for cellulose, break down complex organic molecules into simpler forms that can be absorbed by the organism.
One characteristic feature of saprophytic fungi, like molds, is their hyphal structure. The hyphae are thread-like structures that collectively form mycelium, and at the tip of these hyphae, the enzymes are secreted to break down external organic matter. This external digestion allows saprophytes to absorb nutrients from the decomposed material.
