Webb9 okt. 2009 · On land, plants remove carbon from the atmosphere through photosynthesis. Animals eat plants and either breath out the carbon, or it moves up the food chain. When plants and animals die and decay, they transfer carbon back to the soil. Moving offshore, the ocean takes up carbon through physical and biological processes. 2k文明6官网

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events th… WebbThe geological carbon cycle occurs by geologic processes and describes the much slower flow of carbon between Earth’s nonliving carbon reservoirs. During the geological carbon cycle, carbon moves from rocks on land into the oceans via weathering and rainwater runoff. Carbon also enters oceans from the atmosphere as carbon dioxide dissolves ... Webb10 sep. 2024 · The carbon cycle refers to the myriad processes by which natural systems absorb and emit carbon. Plants and animals use carbon to build their cell structures. Carbon can also be deposited in soils. This is how carbon is absorbed or ‘sequestered’. Stored carbon can be released or emitted through natural respiration or when cell … 2k文明6打不开
