heterotroph

an organism dependent on obtaining organic food from the environment because it is unable to synthesize organic material. All animals, fungi, many bacteria, plants without chloroplasts and a few flowering plants (such as insectivorous plants) are heterotrophs, and they obtain almost all their organic material, either directly or indirectly, from the activity of AUTOTROPHS. See HOLOZOIC, SAPROPHYTE, PARASITE.

Generally, nitrifiers are more sensitive to high temperatures than heterotrophs, and significant nitrification cannot be expected after prolonged exposure to temperatures above 50[degrees]C (Walden and Wright 1995; Sierra and Marban 2000).
A review of the literature suggests that most heterotrophs, such as grasshoppers, show a strong ability to maintain elemental homeostasis via physiological control, and they do this despite changes in the chemical composition of the environment, including their food (Sterner & Elser 2002).
Bacteria that break down organic molecules (such as proteins, carbohydrates, amino acids, and fatty acids) are heterotrophs and acquire these nutrients from other organisms.
A culture of heterotrophs was produced using culture broth and lake water.
This list includes autotrophs (which derive energy from nonbiological sources) as well as heterotrophs (which derive energy by the consumption of organic material, usually other life forms).
2] are called autotrophs, and organisms that get their carbon from organic sources are called organotrophs or heterotrophs.
