An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals because autotrophs produce their own food, they are sometimes called producers encyclopedic entry.
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.
Chemosynthesis, process in which carbohydrates are manufactured from carbon dioxide and water using chemical nutrients as the energy source, rather than the sunlight used for energy in photosynthesis most life on earth is fueled directly or indirectly by sunlight.
See also autotroph autotroph , in biology, an organism capable of synthesizing its own organic substances from inorganic compounds autotrophs produce their own sugars, lipids, and amino acids using carbon dioxide as a source of carbon, and ammonia or nitrates as a source of nitrogen. An autotroph or producer, is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) from simple substances present in its surroundings, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis.
Autotroph vs heterotroph diffen science biology autotrophs are organisms that can produce their own food from the substances available in their surroundings using light ( photosynthesis ) or chemical energy (chemosynthesis. Autotrophs chemosynthesis methane chemosynthesis because chemosynthesis alone is less efficient than photosynthesis or cellular respiration, it cannot be used to power complex multicellular organisms these bacteria often grow in colonies around the plants’ roots, releasing nitrates into the surrounding image below shows the roots.
