• Ecological Hierarchy

  Biosphere>Ecosystem>Community>Population>Species
• Explain each level ecological hierarchy

  Species

  -organism that can interbreed and produce viable offspring

  Population

  -group of individual of some species in the given area

  Community

  -Population of different species interact together within ecosystem

  Ecosystem

  -flow of energy between biotic and abiotic organisms

  Biosphere

  -all ecosystem combined
• *Subfields Ecology

  Organism Ecology

  Study about organisms structure and behavior meet challenges posed by environment
• *Subfields Ecology*

  Population ecology

  Factor that effect how many species in particular area
