chemosynthesis sentence in Hindi
Sentences

- If bacteria can live off of rocks using chemosynthesis as a source of energy, they can live off of oil in a similar way.
- Since chemosynthesis can take place in the absence of sunlight, these organisms are found mostly around hydrothermal vents and other locations rich in inorganic substrate.
- The sclerites may help protect the gastropod from the vent fluid, so that its bacteria can live close to the source of electron donors for chemosynthesis.
- These bacteria use sulfur compounds, particularly hydrogen sulfide, a chemical highly toxic to most known organisms, to produce organic material through the process of chemosynthesis.
- The bacteria derive their energy from chemosynthesis of volcanic sulfur compounds including H 2 S and warm-water solution dripping down from above, producing sulfuric acid.
- Life in the cave has been separated from the outside for the past 5.5 million years and it is based completely on chemosynthesis rather than photosynthesis.
- The food chain is based on chemosynthesis in the form of methane-and sulfur-oxidising bacteria, which in turn release nutrients for fungi and other bacteria.
- This chemosynthesis revolutionized the study of biology and astrobiology by revealing that life need not be sun-dependent; it only requires water and an energy gradient in order to exist.
- Their cumulative energy fixation in carbon compounds ( primary production ) is the basis for the vast majority of oceanic and also many freshwater food webs ( chemosynthesis is a notable exception ).
- In 1897, Wilhelm Pfeffer coined the term " chemosynthesis " for the energy production by oxidation of inorganic substances, in association with autotrophy-what would be named today as chemolithoautotrophy.
- Sunlight is nonexistent, so many organisms such as archaea and extremophiles convert the heat, methane, and sulfur compounds provided by black smokers into energy through a process called chemosynthesis.
- By contrast, the hydrogen compounds used in chemosynthesis are high in energy, so chemosynthesis can take place in the absence of sunlight ( e . g ., around a hydrothermal vent ).
- By contrast, the hydrogen compounds used in chemosynthesis are high in energy, so chemosynthesis can take place in the absence of sunlight ( e . g ., around a hydrothermal vent ).
- Buckminster Fuller first described the concept in his 1970 paper " Cosmic Costing ", contrasting the photosynthesis on which natural capital and sustainable infrastructural capital depend, with the chemosynthesis of extracting and using fossil fuels.
- It principally occurs through the process of photosynthesis, which uses light as its source of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of inorganic chemical compounds as its source of energy.
- Chemoautotrophs, organisms that obtain carbon through chemosynthesis, are phylogenetically diverse, but groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the aquificaeles, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria.
- Further expeditions involved quantitative sampling of habitats in different areas, from the Mediterranean Ridge to the eastern Nile deep-sea fan . have also revealed chemosynthesis-based communities that showed a considerable similarity to the symbiont-bearing fauna of eastern Mediterranean cold seeps.
- This contrasts with holophytic nutrition, in which energy and organic building blocks are obtained through photosynthesis or chemosynthesis, and with saprozoic nutrition, in which digestive enzymes are released externally and the resulting monomers ( small organic molecules ) are absorbed directly from the environment.
- Use of the term " chemosynthesis " reinforces the view that this is feasible by pointing out that several alternate means of creating complex proteins, mineral shells of mollusks and crustaceans, etc ., evolved naturally, not all of them dependent on photosynthesis and a food chain from the sun via chlorophyll.
- 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 ( e . g . hydrogen gas, hydrogen sulfide ) or methane as a source of energy, rather than sunlight, as in photosynthesis.
