<span>It is process through which plants and other photoautotrophs generate carbohydrate and oxygen from carbon dioxide, water and light energy in chloroplast. It is two stage reaction-
1.Light dependent reaction- in this sunlight is absorbed by chlorophyll and converted into chemical energy and stored in the form of NADPH and ATP. It takes place in thylakoid membrane in chloroplast.
2.Light Independent Reaction- in this energized electrons from the light dependent reaction provides the energy to form carbohydrate from carbon dioxide molecules. It is known as Calvin cycle.</span>

Primary succession occurs<span> in essentially lifeless areas or regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. Hope this answers the question.</span>
