Oxidation of organic compounds within an ecosystem
Ecosystem respiration is the sum of all respiration occurring by the living organisms in a specific ecosystem.[1] The two main processes that contribute to ecosystem respiration are photosynthesis and cellular respiration. Photosynthesis uses carbon-dioxide and water, in the presence of sunlight to produce glucose and oxygen whereas cellular respiration uses glucose and oxygen to produce carbon-dioxide, water, and energy. The coordination of inputs and outputs of these two processes creates a completely interconnected system, constituting the underlying functioning of the ecosystems overall respiration.
It is the operation in which the organisms within a specified ecosystem use the process of respiration to convert organic carbon to carbon dioxide. While the amount of respiration is varied upon the type of ecosystem and the community abundance, the mechanism occurs in both aquatic and terrestrial environments.
