Photosynthesis for phototrophs, or chemosynthesis for chemotrophs.
directly from chemical reactions
Photosynthesis
Bacteria that obtain their energy by removing electrons from inorganic molecules, rather than obtaining energy from the sun, are called chemoautotrophic. In general, organisms, that obtain their energy from sunlight are called photoautotrophs.
It is a biological term for an organism that derives energy and carbon from the oxidation of preformed organic compounds. These include fungi, which do not have chloroplasts to use photosynthesis.
Chemoautotrophs (or chemotrophic autotroph), in addition to deriving energy from chemical reactions, synthesize all necessary organic compounds from carbon dioxide. Chemoautotrophs generally only use inorganic energy sources. Most are bacteria or archaea that live in hostile environments such as deep sea vents and are the primary producers in such ecosystems. Evolutionary scientists believe that the first organisms to inhabit Earth were chemoautotrophs that produced oxygen as a by-product and later evolved into both aerobic, animal-like organisms and photosynthetic, plant-like organisms. Chemoautotrophs generally fall into several groups: methanogens, halophiles, sulfur reducers, nitrifiers, anammoxbacteria and thermoacidophiles.
producers get their energy from the sun. They absorb the sun, this process is called photosynthisis.
Light energy from the sun is absorbed by photosystems in chloroplasts. the latin description of the name relates around as photo meaning light, troph means to feed so auto troph means self feeding. so photoautotrophs are self feeding organisms using light. if you need a better answer ask me for more detail and i will be happy to help. hope this helps.
chemoautotrophs
Most Chemoheterotrophs derive energy from organic molecules like glucose.
Bacteria that obtain their energy by removing electrons from inorganic molecules, rather than obtaining energy from the sun, are called chemoautotrophic. In general, organisms, that obtain their energy from sunlight are called photoautotrophs.
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.
It is a biological term for an organism that derives energy and carbon from the oxidation of preformed organic compounds. These include fungi, which do not have chloroplasts to use photosynthesis.
Autotrophs are organisms that can produce their own food using sunlight or inorganic compounds as a source of energy, such as plants. Chemoautotrophs are a specific type of autotrophs that obtain their energy from the oxidation of inorganic chemicals, such as certain bacteria that live in deep-sea hydrothermal vents. Essentially, while all chemoautotrophs are autotrophs, not all autotrophs are chemoautotrophs.
No. Unlike plants, fungi don't have this ability.

Prokaryotes can be classified into four nutritional modes based on how they obtain energy and carbon sources. Photoautotrophs use light as an energy source and carbon dioxide as a carbon source. Chemoautotrophs use inorganic compounds for energy and carbon. Photoheterotrophs use light for energy and organic compounds for carbon, while chemoheterotrophs rely on organic compounds for both energy and carbon.

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.
