What is chemosynthisis?
Chemosynthetic bacteria means bacteria that can make chemical things (synthetic). Basically any bacteria are chemosynthetic - they all product different chemicals as part of their metabolism. There are methanogens that produce methane gas, there are photosynthetic organisms that produce oxygen (like plants, and the ancestry of plants), others can produce nitrogen gas, like those bacteria that live in nodules on legume plants. Other bacteria can produce acids from fermentation like proprionic acid which gives Swiss cheese its nutty flavor. So lots and lots of bacteria are chemosynthetic. It just depends on what you want to produce.
Where do chemosynthetic get energy?
you get it from the sky.
Explain van niel's hypothesis and describe how it contributed to our current understanding of photosynthesis?
Best Answer - Chosen by VotersIngenhousz's hypothesis that photosynthesis produces oxygen by splitting carbon dioxide was refuted about 150 years later by the Dutch-born microbiologist Cornelius van Niel (1897-1985) in America. Van Niel studied photosynthesis in anaerobic bacteria, rather than in higher plants. Like higher plants, these bacteria make carbohydrates during photosynthesis. Unlike plants, they do not produce oxygen during photosynthesis and they use bacteriochlorophyll rather than chlorophyll as a photosynthetic pigment. Van Niel found that all species of photosynthetic bacteria which he studied required an oxidizable substrate. For example, the purple sulfur bacteria use hydrogen sulfide as an oxidizable substrate and the overall equation for photosynthesis in these bacteria is: On the basis of his studies with photosynthetic bacteria, van Niel proposed that the oxygen which plants produce during photosynthesis is derived from water, not from carbon dioxide. In the following years, this hypothesis has proven true. Van Niel's brilliant insight was a major contribution to our modern understanding of photosynthesis
What produces oxygen in?
Photosynthetic leaves of the plants.
What is the difference between chemosynthetic autotroph and a photosynthetic autotroph?
Phototrophs are organisms (usually plants) that carry out photosynthesis to acquire energy. They use the energy from sunlight to convert carbon dioxide and water into organic materials to be utilized in cellular functions such as biosynthesis and respiration. chemotroph are organisms that obtain energy by the oxidation of electron donating molecules in their environments. These molecules can be organic (organotrophs) or inorganic (lithotrophs). The chemotroph designation is in contrast to phototrophs which utilize solar energy. Chemotrophs can be either autotrophic or heterotrophic.
Which is the correct order of organisms in terms of their appearance on Earth?
bacteria, trilobites, lizards, rhinoceros

The two types of organisms are photosynthetic organisms and chemosynthetic organisms?
Autotrophs
What are examples of chemosynthetic bacteria?
Sulphur bacteria and iron bacteria.
Why do photosynthetic sulfur bacteria use hydrogen sulfide?
I am not entirely sure what photosynthetic sulfur bacteria would be, but many chemosynthetic bacteria use hydrogen sulfide as a source of energy (a good example is the ecosystems of underwater sea vents) photosynthetic bacteria rely (as their name suggests) on light from the sun as the source of their energy
What is a photosynthetic or chemosynthetic autotroph that serves as the basic food source in an ecosystem?
Producer
Compare and contrast photosynthetic producers with chemosynthetic producers?
the both have big ole differences
What are non photosynthetic?
Any bacteria, there are no photosynthetic bacteria.
What are non-photosynthetic?
Any bacteria, there are no photosynthetic bacteria.
What is the mode of nutrition in streptococcus?
The mode of nutrition for streptococcus is mainly absorptive, but some are photosynthetic or chemosynthetic.
A photosynthetic or chemosynthetic autotroph that serves as the basic food source in an ecosystem?
answer it? thats why i'm asking you!
Are eubacteria hederotrophic?
Eubacteria is heterotrophic. But then there are two other types that are photosynthetic autotrophs, and chemosynthetic autotrophs.
