What would happen to the ecosystem if the biomass of primary consumers was higher than the biomass of producers? 

• The primary consumers will eat all of the producers...no more organisms to convert light energy to chemical energy (glucose)
• The primary consumers will become the producers and perform photosynthesis 
• The producers will become primary consumers
• This is DEFINITELY not the right answer.
