carbon dioxide
Carbon dioxide (CO2) enters the Calvin cycle from the atmosphere. This CO2 is used by plants during photosynthesis to produce glucose.
All life is based on carbon - it is the main component of biological compounds. It enters life through the atmosphere, through the oceans, and through plants.
Carbon is taken from atmosphere. It is the main source
Goes under the seaCO2 is diffused from atmosphere to the plants. CO2 enters through stomata. Then it enters into cells
Carbon enters the biotic part of the ecosystem through the process of photosynthesis, in which carbon dioxide from the atmosphere and water react to produce glucose (C6H12O6) and oxygen.
