Study Notes

Biotic Factors

  • Biotic factors refer to the living components of an ecosystem.

Niche

  • The niche of an organism encompasses its role and function within its community and environment.

Population

  • The population of a species consists of all individuals of that species residing within a specific geographical area.

Definitions

  • Abiotic Factors: Non-living components of an ecosystem, such as temperature, sunlight, water, and soil.
  • Biotic Factors: Living components of an ecosystem, including plants, animals, fungi, and bacteria.
  • Community: A group of interacting populations of different species living in the same area.
  • Ecosystem: A community of organisms and their physical environment interacting as a functional unit.
  • Niche: The role or function of an organism within its community and environment.
