Some of the photoheterotrophic : a photosynthetic organism (such as a green plant or a cyanobacterium) that utilizes energy from light to synthesize organic molecules Green plants that convert carbon dioxide into carbohydrates in the presence of sunlight are called photoautotrophs, and they are the primary producers in most marine and terrestrial ecosystems. “Chemoheterotroph” is the term for an organism which derives its energy from chemicals, and needs to consume other organisms in order to live. which organism is NOT correctly matched to its energy source? An organism that depends solely on light for its energy and principally on carbon dioxide for its carbon. The hydrogen ion is also important in transporting solutes and driving a flagellar motor. ie. To survive, all living organisms require carbon and energy. For example, under certain conditions some purple sulphur bacteria use organic acids (rather than hydrogen sulphide) as a source of hydrogen. On the contrary, Chemoheterotrophs get their energy through oxidation of pregenerated organic compounds by feeding on other organisms either dead or alive. Photosynthesis - Photoautotrophs use energy from sun to convert water from the soil and carbon dioxide from the air into glucose. The word photoheterotroph derives its meaning from the three words “photo,” “hetero,” and “troph” which mean light, other, and nourishment respectively.
