The water cycle (article) Ecology Khan Academy
WebThe biological carbon cycle occurs through biological processes and describes the relatively quick flow of carbon between the atmosphere and Earth’s ecosystems. Carbon is introduced into food webs by photosynthetic organisms, which convert gaseous \ce {CO2} COX 2 from the atmosphere into biomass. WebVolcanic ash, aerosols, and mineral dust can also be significant phosphate sources, though phosphorus has no real gas phase, unlike other elements such as carbon, nitrogen, and sulfur.

WebIt can be coupled with O 2, in oxidative respiration (2H 2 + O 2 → 2H 2 O), or with oxidized compounds, such as carbon dioxide or sulfate. [5] In an ecosystem, hydrogen can be produced through abiotic and biological processes. The abiotic processes are mainly due to geothermal production [6] and serpentinization. [7] WebThere are both natural carbon dioxide (CO 2) sources and man-made (anthropogenic) CO 2 sources. NATURAL CO2 SOURCES Natural CO 2 sources account for the majority of CO 2 released into the atmosphere. Oceans provide the greatest annual amount of CO 2 of any natural or anthropogenic source. WebBiogenic carbon refers to CO2 sequestered from the atmosphere during feedstock growth and then released during biofuel combustion. Soil can operate as a sink or a source of carbon emissions depending on soil features and agricultural practices. Soils often lose hold of SOC as a result of agriculture activities, releasing CO 2 into the atmosphere. iphone 10 dead won\u0027t turn on
