Partial mycoheterotrophs: The green plants that feed on fungi
(PHYSorg.com Biology)

You probably learned this basic lesson of biology in elementary school: Plants are self-feeders. These so-called autotrophs use the sun`s energy and water to turn carbon dioxide from the air into food through the process known as photosynthesis. Autotrophic organisms sit at the base of every food chain on Earth and sustain all levels of life as we know it.
