This fact is also key in understanding the global greenhouse effect, which occurs with the release of high amounts of carbon dioxide to the atmosphere by hydrocarbon combustion. In the biosphere, both carbon and carbon atoms are added to the food chain via assimilation; first by plants through photosynthesis and then by animals through consumption of the plants.
