What is responsible for high levels of oxygen in Earth's atmosphere a. Photoautotrophs b. photoheterotrophs c.chemoautotrophs d. chemoheterotrophs that perform decomposition e.parasitic chemoheter..?
a. Photoautotrophs. These are organisms like plants, algae, and cyanobacteria that use sunlight to convert carbon dioxide into oxygen through photosynthesis, which ultimately leads to the high levels of oxygen in Earth's atmosphere.
Nonsulfur photosynthetic bacteria use organic compound as?
CARBON SOURCES.... nonsulfur (purple & green) bacteria are photoheterotrophs, so they use organic compounds, such as alcohols, fatty acids, other organic acids and carbs, as sources of carbon. If using Tortora, Funke & Case Microbiology text, then you can read this in Chapter 5!
What is the difference between photoheterotrophs and photoautotrophs?
Photoheterotrophs use organic compounds as their carbon source; photoautotrophs use carbon dioxide as their carbon source.
Are prokaryotes autotrophs?
They can be, Photoautorophs, Photoheterotrophs, Chemoautotrophs or Chemoheterotrophs
How are photoautotrophs and photoheterotrophs?
Photoautotrophs: Bacteria that use sunlight as their energy source and carbon dioxide (as part of photosynthesis) as their carbon source. These bacteria thus obtain all their nourishment through photosynthesis Photoheterotrophs: Bacteria that use sunlight as their energy source and organic compounds from the environment as their carbon source.
Is the Following true or false Photoheterotrophs can either consume organic material from other organisms or perform photosynthesis?
False. Photoheterotrophs are heterotrophic organisms that use light for energy but cannot use carbon dioxide as their sole carbon source. Examples would be purple non-sulfur bacteria, green non-sulfur bacteria, or heliobacteria.SOURCED.A. Bryant & N.-U. Frigaard (November 2006). "Prokaryotic photosynthesis and phototrophy illuminated".

What are photoheterophs?
Photoheterotrophs are organisms that can use light energy for growth but cannot convert carbon dioxide into organic compounds. Instead, they rely on organic compounds from their environment as a carbon source. An example of a photoheterotroph is the purple non-sulfur bacteria.

a. Photoautotrophs. These are organisms like plants, algae, and cyanobacteria that use sunlight to convert carbon dioxide into oxygen through photosynthesis, which ultimately leads to the high levels of oxygen in Earth's atmosphere.
Do Eubacteria have Nutrition?
Yes, Eubacteria are prokaryotic organisms with various nutritional needs. They can be heterotrophic, obtaining nutrients from organic sources, or autotrophic, producing their nutrients through processes like photosynthesis or chemosynthesis. Some Eubacteria can also be symbiotic or parasitic.
What is photohererotrophs?
Photoheterotrophs are organisms that use light as an energy source but require organic compounds as a carbon source for growth and metabolism. They cannot produce their own organic molecules through photosynthesis and must rely on consuming organic material from their environment. Examples include some types of bacteria and certain aquatic protists.
What is a photo-heterotroph?
A photo-heterotroph is an organism that uses light energy to create ATP but must obtain its carbon from organic compounds. Unlike autotrophs, which can use inorganic carbon sources like CO2, photo-heterotrophs rely on organic matter as their carbon source for growth and energy production. Examples of photo-heterotrophs include green non-sulfur bacteria and certain types of purple bacteria.
Hetertroph photo and chemo?
Photo and Chemo in Heterotrophs refer to their way of eating and gathering nutrition. If it using light for energy, it is a photoheterotroph. If it gets its energy from inorganic/organic compounds, it is an chemoheterotroph.
Nonsulfur photosynthetic bacteria use organic compound as?
CARBON SOURCES.... nonsulfur (purple & green) bacteria are photoheterotrophs, so they use organic compounds, such as alcohols, fatty acids, other organic acids and carbs, as sources of carbon. If using Tortora, Funke & Case Microbiology text, then you can read this in Chapter 5!
What is the difference between chemotrophs and chemolithotrophs?
The difference is the way they obtain energy. Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). Photoheterotrophs are heterotrophic organisms that use light for energy, but cannot use carbon dioxide as their sole carbon source.
