Definition noun, plural: autotrophs A organism capable of making nutritive organic molecules from inorganic sources via photosynthesis (involving light energy) or chemosynthesis (involving chemical energy)
Some organisms can carry out photosynthesis, whereas others cannot. An autotroph is an organism that can produce its own food. The Greek roots of the word autotroph mean âselfâ (auto) âfeederâ (troph). Plants are the best-known autotrophs, but others exist, including certain types of bacteria and algae (Figure 1).
