Abiotic Factors

Table of Contents

The world we live in has many ecosystems – from rivers and lakes to forests and valleys. Animals, plants and microorganisms inhabits in these ecosystems. The non-living things like water, air, soil and rocks are also present in them. From an ecological perspective, we can categorize these environmental components into two types – biotic factors and abiotic factors. We shall discover what are abiotic factors in an ecosystem.

What are Abiotic factors?

Abiotic factors are the non-living components of the ecosystem. These include factors such as wind, water, sunlight, soil, temperature and humidity. Abiotic factors can either be chemical or physical components of an environment. Abiotic factors have the potential to affect all living organisms with respect to their growth, reproduction and survival.

Examples of Abiotic factors

The abiotic factors in an ecosystem are as follows:

  • Water
  • Temperature
  • Humidity
  • Atmosphere
  • Light
  • Acidity
  • Soil

Please note, the abiotic factors list may change depending on the ecosystem. For instance, sound waves and pressure can also be considered as an abiotic factor in sub-terrestrial or marine ecosystems.
