Decomposition and Carbon Dioxide Evolution
By this phenomenon, the limited supply of CO2 available for photosynthesis is replenished. Three separate simultaneous processes can be distinguished during organic carbon transformation:
Plant and animal tissue constituents disappear under the influence of microbial enzymes.
New microbial cells are synthesised so that the proteins, polysaccharides and nucleic acids typical of bacteria and fungi appear.
Certain end products of the breakdown are excreted into the surroundings to accumulate or to be further metabolised.
