Abiotic Components

Abiotic components or Abiotic factors are non-living chemical and physical elements of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors and the phenomena associated with them underpin all biology. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms.

Examples of Abiotic Component

Abiotic Component

  1. Water
  2. Climate
  3. Sunlight
  4. Minerals
  5. Temperature

The components abiotic in an ecosystem includes all the physical and chemical elements, which means non-living components.  These components can be different from region to region, from ecosystem to ecosystem.

  • Temperature: Temperature of the air and water affect animals, plants and humans in ecosystems. All living organisms have a tolerance level for temperature range. For example, a human being would die if he stood out in minus 50 degree temperatures for any length of time. Light exposure often affects the temperature. Areas with direct sunlight are warmer.
  • Water: All living organism needs some water intake. Water covers 70 percent of the earth’s surface and falls as rain or snow over land. In an environment with little water, only organisms requiring a small percentage of water can survive. Other animals thrive in conditions with large amounts of water, such as marine animals and plants in oceans. Water is essential to survival, but every organism needs a different amount of water.
  • Sunlight: The sun is constantly giving off radiation. The sun’s radiation is energy in the form of light. We commonly call this sunlight. The sun light useful to photosynthesis and other genetic process.
