The term 'decomposer' originated in the late 20th century from the prefix 'de-' meaning 'down' or 'away from', and 'composer', which refers to an organism that composes or builds organic matter. In ecological sciences, the role of decomposers became more recognized as research revealed their vital part in nutrient cycling. By the 1970s, the concept of food webs highlighted the interconnectedness of producers, consumers, and decomposers in ecosystems underscoring their importance in maintaining ecological balance. The word reflects the function of these organisms in breaking down complex substances into simpler forms that can be reused by other living things, contributing to the sustainability of ecosystems.
