Correct Answer: dead and decaying material

Solution : The correct option is dead and decaying material.

Saprophytes are organisms that feed on decaying organic materials. They are also known as saprotrophs or decomposers. They get their nutrition and energy from decomposing dead and decaying organic matter like dead plants, animals, and other organic debris. Saprophytes produce enzymes during the decomposition process, which break down complex organic compounds into smaller molecules, making the nutrients inside the decaying matter available for their own growth and development. This role is critical in nutrient cycling and organic matter recycling throughout ecosystems.
