An organism that is capable of making and storing food using the sun (or another nonliving) energy sources Plants are autotrophs because they use water, carbon dioxide, and the energy from the sun to make the complex sugars they use as food
An organism capable of synthesizing its own food from inorganic substances using light or chemical energy Examples of autotrophs include plants and some protozoans
{i} microorganism which independently produces the compounds which are necessary for its survival
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
Self-feeder: opposite of heterotroph Organisms that do not feed on other organisms
An organism that synthesizes organic molecules from inorganic starting materials through photosynthesis, or chemosynthesis Autotrophs are ecologically important as they ultimately provide energy for all heterotrophic organisms
Any organism that is able to manufacture its own food Most plants are autotrophs, as are many protists and bacteria Contrast with consumer Autotrophs may be photoautotrophic, using light energy to manufacture food, or chemoautotrophic, using chemical energy
An organism that is independent of outside sources for organic food materials and manufactures its own organic material from inorganic sources
Organisms that obtains food/energy by not eating other organisms For example autotrophs use energy from the sun or obtain energy from inorganic substances Plants are autotrophs, specifically photoautotrophs
An organism capable of utilizing CO2 or carbonates as a sole source of carbon and obtaining energy for carbon reduction and biosynthetic processes from radiant energy (photoautotroph or photolithotroph) or oxidation of inorganic substances (chemoautotroph or chemolithotroph)
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
