Living on dead organic matter is described as what mode of nutrition?

Explanation:
Living on dead organic matter involves releasing enzymes to break down decaying material outside the organism and then absorbing the resulting nutrients. This is called saprophytic nutrition, a form of heterotrophic feeding. Fungi and many bacteria are classic examples, decomposing complex substances like cellulose, proteins, and lignin and taking up the simpler molecules they produce. It differs from autotrophic nutrition, where organisms make their own organic compounds, and from other heterotrophs that must ingest food rather than absorb it after external digestion.
