  • Biotic factors are the living parts of an environment.
  • All living factors within an environment are referred to as biotic factors.
  • Biotic factors are always biological, with food availability being a common example.
  • It's important to list biotic factors and explain how changes in them can affect a community.
  • Abiotic factors are the non-living parts of the environment.
  • The prefix "A" in abiotic means without, so abiotic factors are without biological properties.
  • Abiotic factors are either physical or chemical.
  • Examples of abiotic factors include water, light intensity, wind, and pH.
  • For exams, it's necessary to list abiotic factors and explain how changes in them can affect a community.
