WebPhotosynthetic autotrophs (photoautotrophs) use sunlight as an energy source, whereas chemosynthetic autotrophs (chemoautotrophs) use inorganic molecules as an energy source. Autotrophs are critical for all ecosystems. Without these organisms, energy would not be available to other living organisms and life itself would not be possible. Figure 1. WebAn autotroph is an organism that can produce its own food. The Greek roots of the word autotroph mean “self” ( auto) “feeder” ( troph ). Plants are the best-known autotrophs, but others exist, including certain types of bacteria and algae (Figure 7). Oceanic algae contribute enormous quantities of food and oxygen to global food chains.

WebFeb 23, 2024 · For example, autotrophs comprise the first trophic level of a certain food chain, the heterotrophs that consume those autotrophs make up the second trophic level, and so on. Within each food chain, only about 10% of the amount of energy that is initially available to one trophic level is available to the organisms in the next trophic level.
