Most life on earth is dependent upon photosynthesis, the process by which plants make energy from sunlight however, at hydrothermal vents in the deep ocean a unique ecosystem has evolved in the absence of sunlight, and its source of energy is completely different: chemosynthesis. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (eg, hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis. Even when light gets to a plant, the plant doesn't use all of it it actually uses only certain colors to make photosynthesis happen plants mostly absorb red and blue wavelengths. Availability of water ( plants that live in dry, desert conditions have adopted a waxy coating on their leaves to prevent water loss), temperature (photosynthesis depends on enzymes, if you damage them, the rate will slow or stop) , intensity of light (increase light intensity, increase rate), color of light (chlorophyll absorbs blue and red. Chemosynthesis is a process certain organisms use to obtain energy for the production of food, akin to photosynthesis, but without the use of sunlight the energy comes from the oxidization of inorganic chemicals that the organisms find in their environment.
Chemosynthesis is the conversion of carbon compounds and other molecules into organic compoundsin this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, is oxidized to act as the energy source. Photosynthesis occurs only in green plants or in organisms which have chlorophyll while chemosynthesis occurs only in bacteria photosynthesis needs sun energy as an essential requirement while chemosynthesis does not need solar energy for the process. Chemosynthetic bacteria, unlike plants, obtain their energy from the oxidation of inorganic molecules, rather than photosynthesis chemosynthetic bacteria use inorganic molecules, such as ammonia, molecular hydrogen, sulfur, hydrogen sulfide and ferrous iron, to produce the organic compounds needed for their subsistence. This process is not called photosynthesis (the synthesis of organic matter from light energy) but chemosynthesis (the synthesis of organic matter from chemical energy) these special bacteria are kept as symbionts inside the bodies of deep-sea animals, so some deep-sea communities do not rely on plant matter.
Some of the bacteria that live in the ocean use hydrogen sulfide to power chemosynthesis parasitic plants are unable to make their own food these plants feed off the roots or stems of their hosts. When discussing chemosynthesis vs photosynthesis, one important factor that distinguishes these two processes is the use of sunlight chemosynthesis occurs in darkness, on the seafloor, whereas, photosynthesis requires light energy from the sun to make food.
Chemosynthesis is the use of energy released by inorganic chemical reactions to produce food chemosynthesis is at the heart of deep-sea communities, sustaining life in absolute darkness, where sunlight does not penetrate. An example of chemosynthetic bacteria is thermodesulfovibrio yellowstonii these bacteria are found in yellowstone lake thermal vents and are thermophilic chemosynthetic bacteria. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.
Do humans use chemosynthesis - ayalexgroupcom do humans use chemosynthesis - kimgrafit chemosynthesis - wikipedia, the free encyclopedia use of the term chemosynthesis photosynthesis and chemosynthesis - sea. Plants release o2 when they produce sugar, that's why we call that oxygenic photosyntesis on the contrary, when sulfur bacteria produce sugar, they release elemental sulfur instead, so they don't produce o2 - that's why we call that anoxygenic photosyntesis. Instead, tenebra's plants use chemosynthesis based on the transformation of sulphur oxides lithotrophs that can produce sugars through chemosynthesis make up the base of some food chains it is this chemosynthesis that supports the complex communities that can be found around hydrothermal vents.
Unlike photosynthesis, chemosynthesis does not involve the use of light energy but energy derived from oxidation-reductions that must be adequate for the synthesis of adenosine triphosphate (atp) and that must exceed 10 kcal/mole. Photosynthesis occurs in plants and some bacteria, wherever there is sufficient sunlight - on land, in shallow water, even inside and below clear ice all chemosynthetic organisms use the energy released by chemical reactions to make a sugar, but different species use different pathways.
That mass comes from the air, and photosynthesis is the process that plants use to get it they absorb carbon dioxide (co2) and water (h2o) and, using the energy in sunlight, mush them together into sugars (things of the rough form, c6h12o6. Photosynthesis is the process by which higher plants manufacture dry matter through the aid of chlorophyll pigment, which uses solar energy to produce carbohydrates out of water and carbon dioxide the overall efficiency of this critical process is somewhat low, and its mechanics are.

Photosynthesis and chemosynthesis next photosynthesis is the process by which plants use the sun's energy to make sugar (glucose) for food plants absorb energy. Plants are the most common autotrophs in terrestrial—land—ecosystems all green plant tissues can photosynthesize, but in most plants, but the majority of photosynthesis usually takes place in the leaves. Best answer: chemosynthesis is a process certain organisms use to obtain energy for the production of food, akin to photosynthesis, but without the use of sunlight the energy comes from the oxidization of inorganic chemicals that the organisms find in their environment. Chemosynthesis is a biological process that uses inorganic compounds (rather than sunlight as in photosynthesis) as the energy source to convert carbon compounds and nutrients into organic.
