- Carbon Cycle
- Co2 is absorbed by plants in photosynthasis
- Co2 becomes carbon compounds in plant tissue
- carbon is passed on to consumers down the food chain
- dead organic matter is digested by microorganisms - decomposeres (saprobiontic nutrition)
- carbon returns to air via respiration
- if there's no decomposeres (e.g. in ocean) organic matter is turned into fossil fuels over millions of years
- carbon from fossil fuels is released when they are burnt (combustion)
- photosynthesis removes carbon from the atmosphere
