Ichthyological terms, not general ones.
Natural, ecological process in which organic material is broken down into simpler substances which may then be used by other organisms. Typically biotic and carried out by microbes, worms, and other organisms but can also be abiotic and occur via chemical or physical processes such as oxidation or hydrolysis.

Organism feeding on dead or decaying material aiding the natural process of decomposition by breaking down organic substances which subsequently become nutrients.
In biology, organic debris most often formed via the decomposition of organisms.

A compressed accumulation of partially-decomposed, chiefly vegetable matter typically found in certain marshes, bogs, and peat swamp forests throughout the world. It forms via breakdown of various plants and other organic materials in water when full decomposition is prevented due to localised acidic, anaerobic conditions. As a result of this somewhat specific nature the organisms inhabiting peaty environments are often stenotypic and found nowhere else. Peat can be used as a fuel when dried and thus has industrial importance in some countries. Also used in aquaria, especially in order to simulate blackwater habitats, either in pure, artificially-granulated or liquid extract form.
