An organism, such as a bacterium or protozoan, that obtains its nourishment through the oxidation of inorganic chemical compounds as opposed to photosynthesis
An organism capable of synthesizing its own food from inorganic substances using light as an energy source. Green plants and photosynthetic bacteria are photoautotrophs
organisms which use light for energy, but cannot use carbon dioxide as their sole carbon source. Consequently, they use organic compounds from the environment to satisfy their carbon requirements.
an organism requiring organic compounds for its principal source of food
any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists
an organism which uses an inorganic substrate (usually of mineral origin)
must ingest organic building blocks that they are incapable of creating on their own. Most derive energy from organic molecules like glucose.
respiration in which molecular oxygen is consumed and carbon dioxide and water are produced
Aerobic Respiration
Respiration in which molecular oxygen is not consumed
Anaerobic Respiration
the species that is reduced
Electron Acceptor
the species that is oxidized
Electron Donor
To oxidize (an ammonia compound) into nitric acid, nitrous acid, or any nitrate or nitrite, especially by the action of nitrobacteria
to reduce (nitrates) to nitrites, ammonia, and free nitrogen, as in soil by microorganisms
