(hĕt`ərətrōf'), living organism that obtains its energy from carbohydrates and other organic material. All animals and most bacteria and fungi are heterotrophic. In contrast, autotrophsautotroph
, in biology, an organism capable of synthesizing its own organic substances from inorganic compounds. Autotrophs produce their own sugars, lipids, and amino acids using carbon dioxide as a source of carbon, and ammonia or nitrates as a source of nitrogen.

Our results support that small streams might show catastrophic shifts between net autotrophy and heterotrophy after dredging, reflecting potentially important implications on organic matter cycling and silting up controls in extensive inland flooded areas at low latitudes.
Although giant clams rely greatly on autotrophy as the major source of carbon, heterotrophy is also important to the total energy needed by the clam for respiration and growth (Klumpp et al.
"What we call 'heterotrophy' is the same thing we do after dinner as the bacteria in our gut break down organic matter," Professor Brasier of Oxford University's Department of Earth Sciences, an author of the paper said.

Addition of organic complex nutrients, for example, peptone, yeast extract, malt extract, or beef extract to further boost the biomass propagation, and therefore indirectly, the lipid yield, have been suggested in the reports pertaining to mixotrophy or heterotrophy of several Tetraselmis species [1, 4, 19].
Heterotrophy due to DOC inputs is dominant, and may represent an important driver of denitrification (Goodale et al.
On the one hand, the exuberant cornucopia of filmic inventions implies optimism and faith in the blend of fantasy and technology, as if their relentless combination could expand the expressive potential of film, literature, and life in a systemic loop of heterotrophy. On the other hand, Coover's world also shows the confusion between human and digital and the difficulty to discern and preserve a boundary that is also self-defining and self-protective for the individual.
In addition, elevated C[O.sub.2] can encourage heterotrophy in soil by increasing the flux of carbon (Hungate et al.
