What might happen if all of the autotrophs on the planet suddenly became heterotrophs?
No organism would be able to collect energy from light or carbon from air, and life would end.
Heterotrophs would get their energy from sunlight.
New autotrophs would arise through exogenesis.
Some heterotrophs would become mesotrophs.
Photosynthesis is the basis for food production on Planet Earth. To fill in the blanks
