Autotrophic means self-feeder, i.e. they produce their own food out of raw materials.
Heterotrophic means that they feed on other organisms that have made their own food.
autotrophic certain bacteria that synthesize their own foods.
axon the long extension of a neuron.
bacilli the rod-shaped bacteria (singular, bacillus).
autotrophic Refers to organisms that synthesize their nutrients and obtain their energy from inorganic raw materials.
autotrophs Organisms that synthesize their own nutrients; include some bacteria that are able to synthesize organic molecules from simpler inorganic compounds.

~ algae. Algae capable of photosynthesis and growth using only dissolved inorganic nutrients
Auxotrophic algae. Algae requiring a few organically derived substances, such as vitamins, along with dissolved inorganic nutrients for
~ beings are those that can produce their own food, i.e., that make organic material from inorganic compounds. Heterotrophic beings are those that need to incorporate organic material to nourish themselves. Therefore heterotrophs depend on the production of the autotrophs.
~ nutrition the synthesis of organic molecules from simple inorganic molecules, such as carbon dioxide and water.
Auxin a plant growth substance that acts mainly as a growth stimulator.
Axon the elongated section of a neurone (nerve cell) which carries impulses away from the cell body.
~ Having the ability to synthesize food from inorganic compounds.
~ nutrition Nutrition characterized by the ability to use simple inorganic substances for the synthesis of more complex organic compounds, as in green plants and some bacteria.
An ~ organism, usually a photosynthesizer, that contributes to the net primary productivity of a community.
The ~ symbionts occurring in lichens are simple, photosynthetic organisms commonly and traditionally known as algae. These symbionts include both prokaryotic and eukaryotic organisms.
Chemo~ bacteria and archaea manufacture food using energy secured by oxidizing the sulfur flowing out of the cracks ("black smokers").
Plants are ~, making organic food by photosynthesis.
Most fungi are decomposers with extracellular digestion and absorptive nutrition.
Most animals ingest food and digest it within specialized cavities.
Another, much broader (more inclusive) definition for plant is that it refers to anything that is photoautotrophic — that is, produces its own food from raw inorganic materials and sunlight.
They can be heterotrophic or ~. These two terms mean they either eat other things (hetero) or make food for themselves (auto). Think about it this way: plants are ~ and animals are heterotrophic.
Eugleonphytes, also known as Euglea are an interesting type of protist that is both ~ and heterotrophic. Euglena uses an eyespot to sense light. When light is abundant, it will make its food as an autotroph with photosynthesis.
Plants are also ~, meaning that they produce their own food and do not use other organisms to supply organic nutrients the way animals do.
Carbon source refers to the source of carbon used by an organism for growth and development. An organism is defined as heterotrophic when using organic substrates to get its carbon for growth and development, whereas it is ~, when its source of carbon is carbon dioxide (CO2).
Now, the two major groups are the protozoa and their name means early animals and they're in general are heterotrophic and then there's the algae which are generally ~. Heterotrophic means that you hunt down other things and then you consume them for their food.
In addition to eukaryotes (such as plants and algae), ~ bacteria (such as cyanobacteria) play an important role in the fixation of carbon dioxide into organic compounds. Consumers, in turn, use organic compounds and release carbon dioxide.

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 ~ in nature.
