What is carbon cycle?</h3>
The carbon cycle is the ongoing process through which carbon atoms move back and forth between the atmosphere and the Earth. The amount of carbon in this system does not fluctuate because our planet and its atmosphere are a closed environment. The location of the carbon, whether it is on Earth or in the atmosphere, is continually changing.
Plants use photosynthesis to transport carbon from the atmosphere into the biosphere and move it up the food chain. They make sugar molecules by chemically combining carbon dioxide with oxygen and hydrogen from water using solar energy.
