co2 is required
There is no vitamin that is absorbed through uv rays , but when uv light falls on skin , it produces vitamin D in skin by a photochemical reaction .
Endothermic reaction. See Related Link.
it is the first stage because the product of the light dependent reaction is ATP and NADPH+H+ (Nicotinamide Adenine Dinucleotide Phosphate Hydrogen) and these are required in the light independent reaction (calvin-benson cycle) I hope this helps :DDD
Because it happens only when light present
The proper name for the light-independent reaction is the Calvin Cycle. It is also known as the dark reaction or the carbon fixation process because it does not directly require light to occur.
The dark reaction, also known as the Calvin cycle, can occur during daylight hours because it does not directly require light energy to proceed. It uses the ATP and NADPH generated during the light-dependent reactions to fix carbon dioxide and produce sugars. So even though it doesn't rely on light for its energy source, it still benefits from the products of the light-dependent reactions that happen during the day.
Carbon Dioxide, CO2

Light Development...?
One example of a photolytic reaction that is not a decomposition reaction is the photolysis of water during photosynthesis. In this reaction, light energy is used to split water molecules into oxygen, hydrogen ions, and electrons, which are then used in the production of energy-rich molecules like ATP and NADPH.
During photosynthesis substances such as carbon dioxide and water are used to produce sugars such as glucose. Photosynthesis, as the name implies, uses light from the sun (photons) in order to make this reaction happen. First, the photons reach the thylakoid membranes which are located in the chloroplasts. This is where the light dependent reaction happens. The energy from the photons allows the start of the electron transport chain in which NAPD is reduced into NADPH. This creates a proton gradient which 'powers' ATP synthase so it can produce ATP molecules. Also it is during the light dependent reaction that oxygen is released into the atmosphere. Then, you have the light independent reaction. During this time, a series of reactions convert carbon into glucose.
Subatomic particles such as protons and neutrons interact with each other during a nuclear reaction. They may be released, absorbed, or rearranged to form new elements. These interactions can result in the release of energy and the creation of different isotopes.
