Question

what is the difference between chemosynthetis and photosynthetis​

Answer 1

Answer:

Photosynthesis and chemosynthesis are both processes by which organisms produce food; photosynthesis is powered by sunlight while chemosynthesis runs on chemical energy.

Explanation:

Photosynthesis occurs in plants and some bacteria, wherever there is sufficient sunlight – on land, in shallow water, even inside and below clear ice. All photosynthetic organisms use solar energy to turn carbon dioxide and water into sugar (food) and oxygen: 6CO2 + 6H2O -> C6H12O6 + 6O2.

Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, vent bacteria oxidize hydrogen sulfide, add carbon dioxide and oxygen, and produce sugar, sulfur, and water: CO2 + 4H2S + O2 -> CH20 + 4S + 3H2O. Other bacteria make organic matter by reducing sulfide or oxidizing methane.

$\huge\boxed{\fcolorbox{red}{aqua}{\fcolorbox{aqua}{yellow}{ANSWER}}}$

• photosynthesis and chemosynthesis are reactions that use energy, but the energy source is different.
• In photosynthesis, water is needed to fuel the process; in chemosynthesis, water is an end result of the process.

• The energy source for chemosynthesis may be elemental sulfur, hydrogen sulfide, molecular hydrogen, ammonia, manganese, or iron.
• Examples of chemoautotrophs include bacteria and methanogenic archaea living in deep sea
