Community respiration

CR is an important ecological index as it dictates the amount of production for the higher trophic levels and influence biogeochemical cycles.

[3] The process of cellular respiration consists of a series of metabolic reactions using biological material produced by autotrophic organisms, such as oxygen (O2) and glucose (C6H12O6) to turn its chemical energy into adenosine triphosphate (ATP) which can then be used in other metabolic reactions to power the organism, creating carbon dioxide (CO2) and water (H2O) as a by-product.

Since cellular respiration has been studied in depth across all taxa, research surrounding the process can have many further biological implications.

Community respiration (CR) is an important ecological index used primarily in marine and freshwater aquatic ecosystems and is often tightly coupled with Gross Primary Production (GPP).

The elements can be isolated by using the Electron Transport System (ETS) as a respiratory index and measuring that, which would indicate the rate of cellular respiration.
