    assemblage of populations

5
  • Ecosystem-consists of all the abiotic factors in
    addition to the entire community of species that
    exist in a certain area
  • The emphasis is on energy flow and chemical
    cycling among the biotic and abiotic components

6
  • Biosphere- the global ecosystem (the sum of all
    the planets ecosystem
  • Biome- major types of ecological associations
    that occupy broad geographic regions
