Respuesta :
Heterotrophs depend on autotrophs to obtain energy from the sun. This energy is then passed on to heterotrophs in form of food. Without autotrophs, the sun's energy would not be available to heterotrophs and heterotrophs would eventually die out or find a new way of obtaining energy. hope this helps
Heterotrophs do require autotrophs for survival. If all of the autotrophs died, then the herbivores would die and the carnivores would eat themselves out of existence.
