Select the incorrect match with reference to the structure and function of an ecosystem.

Humification is a process in the decomposition of organic matter in the soil, where organic materials are transformed into humus, which is a stable form of organic matter. This process is important for soil structure and nutrient cycling but does not directly involve energy production. 

Energy production typically refers to the process of generating usable energy within organisms, often through cellular respiration or photosynthesis. This term is not directly related to humification.
