kulstofkredsløb
Kulstofkredsløb refers to the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. It is one of the most important biogeochemical cycles. The Earth's carbon cycle is a process that continuously moves carbon from the atmosphere to the Earth and then back again. Carbon is essential to life on Earth. It is a major component of organic compounds and is also found in the Earth's crust, oceans, and atmosphere.
The carbon cycle involves several key processes. Photosynthesis is the process by which plants, algae, and cyanobacteria
The oceans play a significant role in the carbon cycle, absorbing and releasing carbon dioxide. Marine organisms
