Meaning and Definition
An organism that obtains energy by breaking down organic compounds from other organisms.
A type of heterotroph that derives its energy from chemical reactions involving organic compounds, as opposed to phototrophs (which use light) or lithotrophs (which use inorganic compounds). Most animals, fungi, and many bacteria are chemoheterotrophs.

Common Mistakes When Using “chemoheterotroph”
- Mispronouncing 'heterotroph' as 'heterotrophe'.
- Confusing 'chemoheterotroph' with 'saprophyte' or 'decomposer' (which describe ecological roles, not metabolic pathways).
- Using it to describe plants or algae (which are typically autotrophs).
FAQ
Frequently Asked Questions
Yes, humans are classic examples of chemoheterotrophs. We obtain energy and carbon by consuming and breaking down organic molecules from other organisms (plants and animals).
A decomposer is an ecological role (an organism that breaks down dead matter). A chemoheterotroph is a metabolic classification (how it gets energy and carbon). Most decomposers are chemoheterotrophs, but not all chemoheterotrophs are decomposers (e.g., predators, parasites).
No, by definition. 'Chemo-' specifies a chemical energy source, which excludes light ('photo-'). A photosynthetic organism is a phototroph.
No, it is standardly written as a single word or, less commonly, with a hyphen: chemoheterotroph or chemo-heterotroph. The single word form is more prevalent in modern scientific literature.
An organism that obtains energy by breaking down organic compounds from other organisms.
Chemoheterotroph is usually technical/academic in register.
