1. Myco-heterotrophy refers to the harmonious relationship between particular plants and fungi. 2. Three nutritional strategies are seen in dinoflagellates : phototrophy, mixotrophy, and heterotrophy . 3. Thus, the protist exhibits an unusual life cycle of alternating autotrophy and heterotrophy . 4. Because of this dependence on myco-heterotrophy , they cannot be successfully cultivated. 5. This strategy is known as myco-heterotrophy . 6. Other microbes, living in sediments, may utilise available organic compounds ( heterotrophy ). 7. Facultative mixotrophs, in which autotrophy or heterotrophy is sufficient for nutrition, are classified as amphitrophic. 8. Myco-heterotrophy therefore closely resembles mycorrhiza ( and indeed is thought to have evolved from mycorrhiza ), 9. Some species however contain endo-symbiotic algae and are therefore mixotrophic, i . e . combining autotrophy and heterotrophy ,. 10. Partial ( or facultative ) myco-heterotrophy exists when a plant is capable of photosynthesis, but parasitizes fungi as a supplementary food supply.
