What are the steps of the light-dependent reactions? what are the steps of the light-independent reactions? what is the equation for photosynthesis?

Light-dependent reactions of photoynthesis include steps:

1. Excitation of photosystemsby light energy

2. Production of ATP via an electron transport chain

3. Reduction of NADP+ and the photolysis of water

Light-independent reactions include steps:

1. Carboxylation of ribulose bisphosphate (RuBP)

2. Reduction of glycerate-3-phosphate

3. Regeneration of ribulose bisphosphate

The Chemical Equation of Photosynthesis:

6CO2 + 6H2O > C6H12O6 + 6O2    

In the presence of sunlight

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
