autotrophs
An organism able to build all the complex organic molecules that it requires as its own food source, using only simple inorganic compounds. Plants, and some bacteria are autotrophs.

autotrophs Organisms that synthesize their own nutrients; include some bacteria that are able to synthesize organic molecules from simpler inorganic compounds.

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.

These chemoautotrophs are responsible for the brownish scale that forms inside the tanks of flush toilets.

Autotrophs are organisms that produce their own organic compounds using carbon dioxide from the air or water in which they live. To do this they require an external source of energy.

autotrophs - organisms that need no preformed organic foods
bacterial endospores - see endospores
bacteriophage - virus (phage) that infects a bacterium ...

Eukaryotic autotrophs all have chloroplasts in which the photosynthetic process occurs. The typical chloroplast organization has thylakoids surrounded by a fluid-like stroma. The chloroplast is a membrane bound organelle.

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.

Members of this genus are photoautotrophs that can generate chemical energy through an electron transport chain in the cytoplasmic membrane that is associated with a light-harvesting complex housed in a specialized organelle called the chlorosome.

These photo autotrophs and chemoautotrophs require only the "small" molecules such as CO2, H2O, H2S, nitrates, phosphates, sulfates, etc. as nutrients.

Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs --organisms which make their own food using photosynthesis.

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.

net primary production The total energy converted into biomass by autotrophs. Net primary production is equal to gross primary production less energy lost in maintenance functions of autotrophs.

Any organism too small to be seen by the naked eye, e.g. bacteria, viruses, protozoa, some fungi, and some algae. Microorganisms can be divided into four nutritional groupings: photoautotrophs, photoheterotrophs, chemoautotrophs, ...

Autotroph: An organism that synthesizes organic molecules from inorganic starting materials through photosynthesis or chemosynthesis. Autotrophs are ecologically important as primary producers as they ultimately provide energy for all ...

A diagram of the energy flow between the trophic levels of an ecosystem; plants or other autotrophs (at the base of the pyramid) represent the greatest amount of energy, herbivores next, then primary carnivores, secondary carnivores, etc.

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.
