Everyday
Almost never used. A layperson would describe the concept instead: 'an organism that can both make its own food and eat other things.'
Technical
Standard, precise term in microbiology, oceanography, and protistology. Example: 'Plankton community analysis revealed a significant proportion of facultative mixotrophs.'

FAQ
Frequently Asked Questions
No. A Venus flytrap is a heterotrophic carnivorous plant for nitrogen, but it is primarily an autotroph for energy via photosynthesis. True mixotrophs, like some protists, can use ingested prey directly as a major energy source.
A facultative mixotroph can survive using only one nutritional mode (e.g., just photosynthesis) but utilizes mixotrophy for an advantage. An obligate mixotroph requires both modes simultaneously to survive.
It is extremely rare. While conceptually possible (e.g., 'a mixotrophic economy'), it would likely confuse a general audience due to its highly specialized nature.
There is no single direct antonym, as mixotrophy combines two distinct modes. The pure forms are 'autotroph' (makes its own food) and 'heterotroph' (consumes other organisms). A mixotroph is a combination of both.
An organism that can obtain energy/nutrients from both autotrophic (like photosynthesis) and heterotrophic (like ingesting food) sources.
Mixotroph is usually technical/scientific in register.

Conceptual Metaphor
A HYBRID or VERSATILE ENTITY that combines distinct strategies for survival, like a Swiss Army knife of nutrition.
