Autotrophs are organism which can form its own food.
They obtain water through roots, nitrogen, magnesium, iron and phosphorus from the soil. Nitrogen which is helps in synthesis is taken up in the form of nitrates or nitrites.
Photosynthesis follows as :
" Photosynthesis "
It is the process by which green plant and some other organism use sunlight to synthesize nutrients from carbon dioxide and water.
The main product form here is glucose and by products are oxygen and water.
Here it takes place in chlorophyll and I'm presence of sunlight.
There are two stages of photosynthesis :
1. Light reactions :
It occurs in the grana where photon are absorbed so as to excite electrons of chlorophyll to a higher energy level. These activated elctrons are harnessed to form ATP from the ADP and reduce NADP to NADPH. Wayer ia also spotted here and oxygen is released.
2. Dark reactions :
Calvin cycle occurring in chlorophyll here carbon combine with 5-carbon sugar called ribulose biphospahte. This unstable compound breaks down into 3-carbon compound. This then forms glucose.

autotrophs obtain co2 from atmosphere for the process photosynthesis and n2(nitrogen gas) cannot be used in usual form. it is used in form of n3 or n4(nitrates and nitrites)
