| Parasitic plants evolved from nonparasitic plants and thus underwent an evolutionary transition from autotrophy to heterotrophy, which may be partial or complete. |
| Carbon from atmospheric carbon dioxide is incorporated by photosynthetic or chemosynthetic organisms and converted into carbohydrates through the process of autotrophy. |
| There are many other examples of specialized morphology or life cycles that have evolved either as a necessity for parasitism or as a result of the transition from autotrophy. |
| After greening and probable transition from heterotrophy to autotrophy, root growth rate was enhanced and growth followed a linear pattern. |
| The isolates were able to grow autolithotrophically in mineral medium in the presence of sulfur, hydrogen and CO2 by hydrogen sulfur autotrophy. |
| They consider that early achievement of autotrophy is a major feature of structures with a high degree of foliarization. |
