Lake metabolism represents a lake's balance between carbon fixation (gross primary production) and biological carbon oxidation (ecosystem respiration). [1] Whole-lake metabolism includes the carbon fixation and oxidation from all organism within the lake , from bacteria to fishes , and is typically estimated by measuring changes in dissolved ...
The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, ... Lakes, reservoirs, ...
The Oceanic carbon cycle is a central process to the global carbon cycle and contains both inorganic carbon (carbon not associated with a living thing, such as carbon dioxide) and organic carbon (carbon that is, or has been, incorporated into a living thing). Part of the marine carbon cycle transforms carbon between non-living and living matter.
A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...
Lakes are the final resting place for many of the Earth's plants – and these organic graveyards are about to get a whole lot busier. Freshwater lakes already emit a quarter of global carbon ...

Lake Shala, in the East African Rift Valley. A soda lake or alkaline lake is a lake on the strongly alkaline side of neutrality, typically with a pH value between 9 and 12. They are characterized by high concentrations of carbonate salts, typically sodium carbonate (and related salt complexes), giving rise to their alkalinity.
Lakes are commonly known to be important sinks in the carbon cycle. Dystrophic lakes are typically net heterotrophic due to the large amount of bacterial respiration outweighing phytoplankton photosynthesis, meaning that dystrophic lakes are larger carbon sources than clear lakes, emitting carbon into the atmosphere.
