Photosynthesis in Nature
Transforms solar energy into chemical energy.
CO2 and H2O into Glucose
CO2 is carbon source and light is energy source.

Producers
Plants, Algae and other autotrophs are the producers in the ecosystem.
Autotrophs synthesize organic molecules from inorganic raw materials.
Heterotrophs acquire organic molecules from compounds made by other organisms. (consumers, decomposers)
