Specification 4.7.2.2 · Paper 2
Revise: Cycling of Materials in EcosystemsThe carbon cycle is essential because it supplies the carbon needed to build new organisms. Photosynthesis brings carbon into the living world, feeding transfers it between organisms, and respiration returns it to the atmosphere for reuse.
Paper 1, Paper 2
The movement and reuse of carbon between organisms and non-living stores through processes including photosynthesis, feeding, respiration, decomposition and combustion.
Revise: Ecosystem material cycling and the carbon cycleThe carbon cycle transfers carbon between stores, making it available for reuse rather than leaving it permanently locked in dead organisms and waste.
