heterotroph

(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.

Among the microbiota that inhabit the MCM lakes are microbial eukaryotes, mainly protists representing a broad range of evolutionary lineages inclusive of phototrophs, mixotrophs, and heterotrophs (Kong et al., 2012; Thurman et al., 2012).
However, in a previous study of crude oil polluted and unpolluted soil samples by Chikere and Chijioke-Osiji (2006), it was found that hydrocarbon utiliser population were higher than the heterotrophs.
Although none of the samples analysed revealed the presence of faecal coliforms, the high level of the heterotrophs in the sachet water questions the quality of sachet water when compared to that of the bottled water.

At the ecosystem scale, FLUXNET towers measure net ecosystem C[O.sub.2] exchange (NEE), which is equal to GPP minus ecosystem respiration [70] (i.e., the quantity of C[O.sub.2] respired by both autotrophs (plants) and heterotrophs (primarily microbes)).
Such rapid release can be an energy source for heterotrophs and can enhance [N.sub.2]O emissions later on.
