Organisms and Survival

  • Organisms compete with each other for resources
  • We can break down the factors which affect an organism into two groups:
    • Biotic: living factors
    • Abiotic: non-living factors

Biotic Factors

Biotic describes a living component of an ecosystem

  • All living things (plants, animals, fungi, bacteria)

Abiotic Factors

Non-living chemical and physical factors in the environment

  • Water, light wind, soil, humidity, minerals, gases, pH, salinity
