Ecology and the Biosphere

• Ecology is the study of
• interactions between
• organisms and
• the environment.
• It is not the same thing as environmentalism,
• but the two are related.

Ecology and the Biosphere

• Population individuals of the same species
• Community all of the species that live in an
  area
• Ecosystem abiotic factors as well as the
  community
• Biosphere the global ecosystem.

Ecology and the Biosphere

• Ecosystem ecology deals with energy flow and
  chemical cycling among biotic and abiotic
  components.
