Compare with heterotroph.Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs - organisms which make their own food using photosynthesis.... These developmental differences between autotrophs and parasites suggest that the functions of photoreceptors differ among autotrophs, hemiparasites, and holoparasites. It is a true autotroph and uses only two sources for its metabolism: carbon dioxide as its source for carbon and hydrogen as an energy source. Derivatives autotrophic /ˌɔːtəˈtrɒfɪk / /ˌɔːtəˈtrəʊfɪk/ adjective ... Physiologically, plant conversion or seedling development involves a transition from the heterotrophic embryo to an autotrophic plant. These differences correlate with differentiated function as heterotrophic, autotrophic and transport pathway components of the leaf. Recently there has been discussion about the metabolic state of the ocean, with arguments questioning whether the open ocean is net autotrophic or net heterotrophic. autotrophy noun ... After greening and probable transition from heterotrophy to autotrophy, root growth rate was enhanced and growth followed a linear pattern. This period is followed by post-germinative growth that leads to seedling establishment and the acquisition of autotrophy. They consider that early achievement of autotrophy is a major feature of structures with a high degree of foliarization.
