autotrophic
capable of self-nourishment by using chemical elements for food, for example green plants; contrast to heterotrophic

Autotrophs are a vital part of the food chain. They take energy from the sun or from inorganic sources and convert it into a form (organic molecules) that they use to carry out biological functions including cell growth; ...
autotroph -- Any organism that is able to manufacture its own food. Most plants are autotrophs, as are many protists and bacteria. Contrast with consumer.
Autotroph: An organism that synthesizes organic molecules from inorganic starting materials through photosynthesis or chemosynthesis.
Autotroph
An organism which does not require any organic carbon for its energy source or for its growth.
Auxotroph
A mutant that will only grow when a particular nutritional requirement (e.g. amino acid, nucleotide, or vitamin) is provided.
Autotroph an organism‚ such as a plant‚ which makes its own food
(auto = self; troph = food‚ nourish‚ nourishment) ...
autotrophs Organisms that synthesize their own nutrients; include some bacteria that are able to synthesize organic molecules from simpler inorganic compounds.
autotroph
(aw-toh-trohf) [Gk. autos, self + trophos, feeder]
An organism that obtains organic food molecules without eating other organisms.
Autotrophs Photosynthetic organisms that synthesize glucose from carbon dioxide and water, by using sunlight as an energy source; the glucose is then used as a fuel for cellular metabolism.
This chemoautotroph oxidizes NH3 (produced from proteins by decay bacteria) to nitrites (NO2−). This provides the energy to drive their anabolic reactions.

Autotroph (self-feeder): an organism that makes its own food, it converts energy from an inorganic source in one of two ways.
autotroph An organism that makes its organic nutrients from inorganic raw materials by using an external energy source, such as light energy.
autotrophic Having the ability to synthesize food from inorganic compounds.
As one of the few strictly autotrophic bacteria currently being sequenced, N.
Autotrophs are "self feeders" that use light or chemical energy to make food. Plants are an example of autotrophs. In contrast, heterotrophs ("other feeders") obtain energy from other autotrophs or heterotrophs.
Carbon dioxide dissolved in the ocean is their source of carbon; they are autotrophs. Organic material from decomposing phototrophs is not abundant, so these organisms rely on inorganic sources for energy.
These photo autotrophs and chemoautotrophs require only the "small" molecules such as CO2, H2O, H2S, nitrates, phosphates, sulfates, etc. as nutrients.
Nutrition: autotrophic (photosynthesis, chemosynthesis), aerobic heterotrophs

Monerans are classified into two phyla, or groups, autotrophs, and heterotrophs. Autotrophs are able to create their own food, similar to plants. Heterotrophs can not create their own food, and so must rely on autotrophs as their food source.
[29] Plants and other autotrophs use solar energy via a process known as photosynthesis to convert raw materials into organic molecules, such as ATP, whose bonds can be broken to release energy.
They can be heterotrophic or autotrophic. These two terms mean they either eat other things (hetero) or make food for themselves (auto). Think about it this way: plants are autotrophic and animals are heterotrophic.
Cyanobacteria: Unicellular, photosynthetic (photo-autotroph) prokaryote (in the Kingdom Monera). Formerly known as blue-green algae. It contains chlorophyll a but not chloroplast. They reproduce by fission and never sexually.
This includes species that are found in decaying material as well as those that utilize fermentation or respiration. Bacteria that create their own energy, fueled by light or through chemical reactions, are autotrophs.
These organisms contain cell walls; plasmodesmata which are required for intercellular activity; plastids with double membranes; and contain photosynthetic pigments thus they are capable of photosynthesis, and are therefore autotrophic in nature.
