Alternative form of autotrophic [(biology) Relating to the production of organic compounds from carbon dioxide as a carbon source, using either light or reactions of inorganic chemical compounds, as a source of energy.]
Alternative form of chemoautotrophic [(biology, of an organism) obtaining its nutrition through the oxidation of non-organic compounds (or other chemical processes); as opposed to the process of photosynthesis.]
(biology) A mode of growth in which CO₂ is the exclusive source of assimilated carbon, and energy is derived from chemical processes rather than light.
the production of carbohydrates and other compounds from simple compounds such as carbon dioxide, using the oxidation of chemical nutrients as a source of energy rather than sunlight; it is limited to certain bacteria and fungi
A heterotrophic organism that uses light for energy but cannot use carbon dioxide as its sole carbon source and thus uses organic compounds from the environment.
(biology) The light-dependent release of carbon dioxide and uptake of oxygen in photosynthetic organisms as an unavoidable side reaction of photosynthesis.
(biology) Describing an organism that oxidizes sulfur compounds as a major part of its metabolism

feature. We've grouped words and phrases into thousands of clusters
based on a statistical analysis of how they are used in writing. Some
of the words and concepts may be vulgar or offensive. The names of the
clusters were written automatically and may not precisely describe
