Mixotrophy is a nutritional strategy where an organism can obtain energy and carbon from more than one source. This means an organism can perform photosynthesis, like plants, to produce its own food using sunlight, but can also absorb or ingest organic compounds from its environment, similar to heterotrophs. Organisms exhibiting mixotrophy are found across various groups, including bacteria, algae, and protists.

The specific combination of nutritional modes can vary. Some mixotrophs primarily rely on photosynthesis but supplement their diet with organic matter when light is scarce or when certain nutrients are limited. Others may predominantly consume organic matter but can photosynthesize under favorable light conditions. This flexibility allows mixotrophic organisms to thrive in a wider range of environmental conditions and exploit diverse resources.

Mixotrophy plays a significant role in many ecosystems, particularly aquatic environments. By utilizing both autotrophic and heterotrophic pathways, mixotrophs can contribute to nutrient cycling and act as both primary producers and consumers. Their ability to adapt their feeding strategy can influence population dynamics and the overall structure of microbial communities. Research into mixotrophy continues to reveal the complexity and adaptability of life.
