A mixotroph is an organism that uses a mix of different sources of energy and carbon, instead of having a single trophic mode. Mixotrophs are situated somewhere on the continuum from complete autotrophy to complete heterotrophy. It is estimated that mixotrophs comprise more than half of all microscopic plankton. There are two types of eukaryotic mixotrophs. There are those with their own chloroplasts – including those with endosymbionts providing the chloroplasts. And there are those that acquire them through kleptoplasty, or through symbiotic associations with prey, or through 'enslavement' of the prey's organelles.
Possible combinations include photo- and chemotrophy, besides litho- and organotrophy, the latter including osmotrophy, phagotrophy and myzocytosis. Mixotrophs can be either eukaryotic or prokaryotic. Mixotrophs can take advantage of different environmental conditions.
