Key Concepts & Definitions

  • Organism: An individual living entity.
  • Population: A group of individuals belonging to the same species inhabiting a specific geographical area.
  • Community: An assemblage of populations of different species living and interacting within a shared environment.
  • Ecosystem: A functional system comprising a community and its non-living environment, with complex interactions between them.
  • Landscape: A heterogeneous area consisting of an array of interacting ecosystems.
  • Biome: A large, naturally occurring community of flora and fauna occupying a major habitat type.
  • Biosphere: The sum total of all living organisms on Earth and the totality of the environments they inhabit.
