Abiotic (factor) Non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.
Prokaryotic/Prokaryote A microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.
Eukaryotic/Eukaryote Any cell or organism that possesses a clearly defined nucleus.
Unicellular Consisting of a single cell.
Multicellular Having or consisting of many cells.
Autotrophic/Autotroph An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Heterotrophic/Heterotroph An organism deriving its nutritional requirements from complex organic substances.
