Biodegradability
When natural organic materials go into the ground, they tend to decompose progressively before they disappear. This is very important for the environment, which has to get rid of waste to make room for new life. Photosynthetic organisms like trees, plants and algae, absorb carbon dioxide from the atmosphere. Using the suns energy, they synthesize sugars and a whole range of other substances present in nature.
The flow of substances and energy passes along the food chain from the plants to the herbivores, and from these, to carnivores. However, this mechanism would quickly become blocked if the opposite process did not exist, that is, if it was not possible to release carbon dioxide from organic material. So, in natural equilibrium, the process of biodegradation is as important as that of photosynthesis. Micro-organisms play an important role in biodegradation they are present in every environment and fed by organic waste. Thus, organic material is transformed back into carbon dioxide thereby completing the natural cycle.
