- Producers (plants, algae, cyanobacteria) take up atmospheric or dissolved CO2 by photosynthesis and convert it into organic carbon (biomass).
- Consumers (herbivores, carnivores) transfer that organic carbon through food webs by eating producers and other consumers.
- All organisms respire, returning CO2 to the atmosphere or water as they break down organic carbon for energy.
- Decomposers (bacteria, fungi) break down dead plants and animals, releasing CO2 (and methane under anaerobic conditions) and recycling nutrients into soils and sediments.
- Over long timescales, some organic carbon becomes buried and forms fossil fuels or carbonate rocks, which can later release carbon through combustion or geological processes.
