Organotroph

Organotrophie (Greek τροφή = nutrition) term used in biology to cover the needs of living beings of reducing agents in organic matter.

Reducing agents are required:

• Related to the change in building materials for syntheses of endogenous substances,
• Related to the energy metabolism chemotropher critters for energy-yielding redox reactions.

The adjective to " Organotrophie " is " organotroph " ( organotroph creatures organotropher metabolism).

If the energy demand organotropher creatures covered from exergonic conversion processes ( Chemotrophie ), so it is called an Chemoorganotrophie, it is, however, covered from light ( prototrophy ), so it is called an Photoorganotrophie.

Examples of chemoorganotrophic living beings: animals, humans, fungi, many bacteria

Example of photoorganotrophe beings: the bacterium Rhodospirillum

In general, use organotroph creatures organic substances, not only as a reducing agent but also as starting materials for the construction of the body's own substances, less energy has to be expended as when using inorganic building material sources. It refers to the use of organic materials as a building material sources as heterotrophy.
