A "self-nourishing" organism. Any organism that obtains its energy from simple chemical reactions. Green plants, which make their own food through photosynthesis, are autotrophs.
An organism capable of using carbon dioxide or carbonates as the sole source of carbon rather than organic matter. Obtains energy from the oxidation of inorganic elements or compounds such as iron, sulphur, hydrogen, ammonium, nitrites or from radiant energy.
an organism that produces its own nutrients, usually through photosynthesis.
(au´ tow trow´ fik) [Gr. autos: self + trophe: food] • An organism that is capable of living exclusively on inorganic materials, water, and some energy source such as sunlight or chemically reduced matter. (Contrast with heterotroph.)
Organisms than can use carbon dioxide as their sole source of carbon. See Heterotroph.
An organism that is independent of outside sources for organic food materials and manufactures its own organic material from inorganic sources.
An organism that synthesizes food molecules from inorganic molecules by using an external energy source, such as light energy.
(Greek, autos = self + trophos = feeder) An organism that makes its own organic molecules from simple inorganic compounds (like carbon dioxide water and ammonia).
An organism, such as a plant or alga, that manufactures its own food using light energy (photosynthesis) or chemical energy (chemosynthesis).
any organism that obtains carbon directly from carbon dioxide (C02) — — CLOSE
Organism that is able to utilize carbon dioxide as a carbon source.
Self-feeder: opposite of heterotroph. Organisms that do not feed on other organisms.
organisms able to synthesize organic matter, and thereby make their own food, from carbon dioxide with sunlight as the energy source (photosynthesis).
An organism capable of synthesizing the organic nutrients it needs from the mineral compounds present in nature. Plants and many bacteria are autotrophs or producers. Autotrophs do not need to obtain their nutrients from other living organisms. By contrast, heterotrophs cannot make their own food and so they feed on the tissues of other organisms.
an organism which can make its own energy
an organism capable of synthesizing its own organic substances from inorganic compounds
an organism that can make its own food
an organism that is capable of synthesizing its own food from inorganic substances, using light or chemical energy
an organism that makes its own food from inorganic substances
an organism that makes organic molecules from inorganic nutrients
an organism that only needs carbon dioxide as its carbon source, and a heterotroph is an organism that requires at least one organic nutrient as a source of carbon for making other organic compounds
an organism that produces its own organic compounds from inorganic substances (e
an organism that uses solar energy or energy from inorganic chemicals to make organic molecules
An organism that needs only simple inorganic compounds to grow, such as carbon dioxide. Most plants and some bacteria are autotrophic.
an organism that makes organic material from inorganic material; a primary producer; examples include plants, phytoplankton, and some bacteria
An organism having the capacity to "fix" inorganic carbon (CO2) [incorporate it into more reduced carbon compounds] and use CO2 as sole carbon source for growth.
(ic) AW-toe-trof An organism that manufactures nutrients using energy from the environment. 14, 112, 146
All organisms e.g. plants, that can live on very simple carbon and nitrogen sources, such as carbon dioxide and ammonia.
An organism which does not require any organic carbon for its energy source or for its growth.
an organism capable of producing organic material from inorganic chemicals and an energy source
an organism which can nourish itself.
Plants and bacteria that can synthesize organic compounds from inorganic nutrients.
Any organism that is able to manufacture its own food. Most plants are autotrophs, as are many protists and bacteria. Autotrophs may be photoautotrophic, using light energy to manufacture food, or chemoautotrophic, using chemical energy.
A microorganism that synthesizes all organic molecules from inorganic sources.
An organism that can get energy directly from sunlight through the process of photosynthesis.
(pronounced AW-toh-trofe) An autotroph (or producer) is an organism that makes its own food from light energy or chemical energy without eating. Most green plants, many protists (one-celled organisms like slime molds) and most bacteria are autotrophs. Autotrophs are the base of the food chain.

an organism that can utilize CO2 as its sole source of carbon; derives energy from the oxidation of inorganic material (e.g. sulfides) or from photosynthesis; organism that does not feed on pre-formed organics.
An organism that is self-nourished, able to build organic substances from inorganic substances; a producer. Back to top of Glossary page
an organism that obtains energy from the sun and materials from inorganic sources, contrast with heterotroph.
is an organism capable of feeding on and producing organic substance using inorganic substances. It is a characteristic common to all green plants that perform chlorophyll photosynthesis.
An organism that satisfies its need for organic food molecules by using the energy of the sun, or of the oxidation of inorganic substances, to convert inorganic molecules into organic molecules. Green plants are autotrophs.
An organism capable of synthesizing its own food from inorganic substances using light or chemical energy. Examples of autotrophs include plants and some protozoans.
an organism which obtains energy from inorganic sources, sunlight or the oxidation of inorganic chemicals.
An autotroph (from the Greek autos = self and trophe = nutrition) is an organism that produces complex organic compounds from simple molecules and an external source of energy, such as light or chemical reactions of inorganic compounds. Autotrophs are considered producers in a food chain. Plants and other organisms that carry out photosynthesis are phototrophs (or photoautotrophs).
