Photosynthesisand Chemosynthesis

Chemosynthesisis the process through which a plant produces organic compoundsthrough the use of energy from inorganic chemical reactions. On theother hand, photosynthesis is the process through which a plantproduces organic compounds by using sunlight energy.

Themain similarity of the two processes is that they both occur inplants as a way of generating food. In addition, the two processesuse inorganic compounds to produce organic compounds (Campbell,2008).In addition, the two processes also produce glucose as part of themain product. These similarities make each of the two processesimportant in plant life as well as the in the ecosystem.

However,the two processes have basic differences that define their existence.First, chemosynthesis is powered by inorganic chemicals whilephotosynthesis is powered by natural sunlight (Campbell,2008).Therefore, chemosynthesis occurs in plants that are in deep seas andis meant to provide energy to sustain plant life even in darkregions. Photosynthesis on the other hand is the primary processthrough which plants in sunlight combine minerals and sunlight toproduce primary energy that sustains the ecosystem. In terms of theprocess, photosynthesis has one formula: CO2&nbsp+ 6H2O to giveC6H12O6&nbsp+ 6O2 (Campbell,2008).On the other hand, chemosynthetic organisms utilize the product of chemical reactions to produce sugar. Moreover, the process ofphotosynthesis produces oxygen gas while chemosynthesis producessulfur as the resultant gas.

Photosynthesisis the most significant step in regard to harnessing energy. This isbecause the process produces the most amount of energy in relation tothe inputs used. Due to the use of sunlight energy, thephotosynthesis uses all the inputs to produce complete outputs.Moreover, photosynthesis has more beneficial impacts on the ecosystemby consuming carbon dioxide and producing oxygen.
