This can be represented by the general equation: AB A + B. Beetles and flies eat anything softer that remains, and mites and moth larvae digest the hair. Anaerobic Digestion. A growing number of scientists view a corpse as the cornerstone of a vast and complex ecosystem, which emerges soon after death and flourishes and evolves as decomposition proceeds. (1) Fragmentation: It is the first step in the process of decomposition. Harmful algal blooms can occur in lakes, reservoirs, rivers, ponds, bays and coastal waters, and the toxins they produce can be harmful to human health and aquatic life. DO begins to rise as decomposition has stopped 5. This is because cold water sinks below less dense warm water found at the surface. Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with SunAgri and INRAE in Avignon between 2019 and 2022. Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces.
