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.

Heterotrophs, however, may have evolved from autotrophs, so the line 'autotrophs began to drool' could be taken as a poetic way of saying that autotrophs evolved into heterotrophs, with the ability not only to use external food sources, but to drool at the prospect of eating them.
The study was performed on aerobic heterotrophs contained in test-tubes under the sterile conditions; and the impact of chemical additives was analysed doublechecking all samples.
