Members of the ecosystem can be divided into these categories:

    eats herbivores
   Tertiary Consumera carnivore: one who eats carnivores and herbivores
    
    detrivore: one who eats dead and decaying things
    decomposer: Fungi and Microbes: consume decaying things and breaks them down into 
          elements and  compounds.  Decomposers cause the biodegradation of other organisms
