requiring ready formed organic food.
species that acquire food from organic matter.
Obtaining nourishment from outside sources, specifically requiring complex organic compounds of nitrogen and carbon for metabolic synthesis.
utilising organic materials (formed by other organisms) as nutrients; cf. autotrophic.
obtaining organic food by eating other organisms or their by-products
Describing consumers, organisms that cannot synthesize food from inorganic materials and therefore must use the bodies of other organisms as a source of energy and body-building materials.
Relating to an organism that must feed on organic materials formed by other organisms in order to obtain energy; contrast with autotroph. Includes animals, fungi, and many unicellular organisms.
Any organism that consumes organic matter as a source of energy. Such an organism is said to be beterotrophic.
A group of organisms which obtain carbon for synthesis from other organic matter or proteins.
requiring organic compounds of carbon and nitrogen for nourishment; "most animals are heterotrophic"
plants that depend on other organisms for nourishment
Organisms that feed on organic matter from external sources, and are osmotrophic or phagotrophic
an organism that cannot produce its own energy. A heterotrophic organism must obtain its energy from external sources (by eating other organisms). See autotrophic.
obtaining nourishment from organic substances, not from food produced within the organism.
designating or typical of organisms that derive carbon for the manufacture of cell mass from organic matter.
Refers to organisms, such as animals, that depend on preformed organic molecules from the environment (or another organism) as a source of nutrients/energy.
Refers to the ability of an organism to manufacture its own food. It must obtain it from other organisms, living or dead, and it is said to depend on external nourishment.
Obtaining energy and carbon for growth from organic materials
Capable of deriving energy for life processes only from the decomposition of organic compounds.
Of or relating to heterotrophs, organisms that cannot synthesize their own food and are dependent on complex organic substances for nutrition (e.g., fish, humans).
obtain nourishment from organic substances rather than inorganic materials or the sun
Obtaining nourishment from exogenous organic material (all animals).
Any organim that eats other organisms in order to satisfy it's nutritional requirements
heteros, other + trophe, nourishment.
Requiring organic substrates for growth and development; being incapable of synthesizing required organic materials from inorganic sources. ( 20)
