What would happen if a decomposer is removed from the ecosystem?

• Nothing
• The ecosystem would eventually die
• Only the producers would be affected
• Only the consumers would be affected

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.
