What would life be like for autotrophs if there were no heterotrophs?

Hey there! Welcome to openstudy! consider reading the CoC: http://openstudy.com/code-of-conduct Heres a link that will help you get to know the site better: http://openstudy.com/study#/updates/548c04e1e4b0f2fbdc23dd6c

do you know what autotrophs and heterotrophs are?

OpenStudy (king.void.):

A heterotroph is an organism that cannot fix carbon and uses organic carbon for growth. Heterotrophs can be further divided based on how they obtain energy; if the heterotroph uses light for energy, then it is considered a photoheterotroph, while if the heterotroph uses chemical energy, it is considered a chemoheterotroph.

OpenStudy (king.void.):

An autotroph or "producer", is an organism that produces complex organic compounds from simple substances present in its surroundings, generally using energy from light or inorganic chemical reactions. They are the producers in a food chain, such as plants on land or algae in water, in contrast to heterotrophs as consumers of autotrophs. They do not need a living energy or organic carbon source. Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and also create a store of chemical energy. Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfide. Phototrophs, a type of autotroph, convert physical energy from sunlight into chemical energy in the form of reduced carbon

OpenStudy (king.void.):

So technically all that means there will be animal life on earth.

@king.void I am a bit confused by your last statement.
