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.
certain bacteria that synthesize their own foods.
axon the long extension of a neuron.
bacilli the rod-shaped bacteria (singular, bacillus).
Autotrophic algae: Algae capable of photosynthesis and growth using only dissolved inorganic nutrients.
Refers to organisms that synthesize their nutrients and obtain their energy from inorganic raw materials.
Autotrophic 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.
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 autotrophic 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.
Chemoautotrophic bacteria and archaea manufacture food using energy secured by oxidizing the sulfur flowing out of the cracks ("black smokers").

Plants are autotrophic, 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.
lichens organisms composed of a fungus (sac or club fungus) and a photosynthetic unicellular organism (e.g., a cyanobacterium or alga) in a symbiotic relationship; ...
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.
Plants are also autotrophic, meaning that they produce their own food and do not use other organisms to supply organic nutrients the way animals do.
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 autotrophic.
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.
Members of the genus Ignicoccus are the only obligatory anaerobic chemolithoautotrophic sulfur reducers within the Desulfurococcales, ...
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.
