| This photosynthetic control of cell-cycle progression is similar to the nutritional control of heterotrophs. |
| The result, especially when heterotrophs are preyed upon by other heterotrophs, is a food chain. |
| All protozoans engage in heterotrophy, but not all protozoans are exclusive heterotrophs. |
| They are heterotrophs that mostly ingest food into a specialized cavity, where it is digested. |
| Endosymbiosis of green algal unicells with two different heterotrophs led to euglenoids and to chlororachniophytes. |
| Unlike plants, animals are heterotrophs which means they are unable to live on inorganic nutrients alone. |
