Actinobacteria sp. are fermenting organisms, which do not require oxygen to survive. These organisms break down organic material and convert it to inorganic material. Which part of the carbon cycle does this describe?

The organisms break down organic material and return its carbon to inorganic forms, which is decomposition. Fermentation can occur without oxygen, but the key process described is the breakdown of dead or waste organic matter. Photosynthesis and assimilation take in carbon, while respiration releases carbon dioxide as organisms use energy.
