Carbon dioxide is the source of carbon. It is reduced to glucose
During photosynthesis, plants use carbon dioxide (CO2) as a carbon source to produce sugars for energy. Carbon dioxide enters the plant through small openings on the leaves called stomata and is converted into sugars through the process of photosynthesis.
Yes, ethanol releases carbon dioxide when it is used as a fuel source.
A carbon source is a process that releases carbon dioxide into the atmosphere, while a carbon sink is a process that absorbs and stores carbon dioxide.
In the carbon cycle, a carbon source releases carbon dioxide into the atmosphere, while a carbon sink absorbs and stores carbon dioxide from the atmosphere.
CO2 is the source of carbon.
Carbon dioxide (CO2) serves as the carbon source for photosynthesis. Plants absorb carbon dioxide from the atmosphere and use it in combination with water and sunlight to produce glucose and oxygen through the process of photosynthesis.
Volcanoes are an exclusively natural source of carbon dioxide, releasing the gas during eruptions. This carbon dioxide can contribute to the greenhouse effect and affects the Earth's climate.
The source of carbon in glucose resulting from photosynthesis is carbon dioxide (CO2) taken in from the atmosphere. During the process of photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose and oxygen. The carbon atoms in glucose come from the carbon dioxide molecules that plants absorb.
