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 produces carbon dioxide, which other plants use to make sugar. Photosynthesis absorbs oxygen from the air, which reduces the rate of climate change. Autotrophs absorb energy from the sun to make sugars for their own use.
