Biotic Factors

The environment that we live in has many components. These include air, water, animals, plants, trees, mountains and more. Moreover, we can broadly classify these components into two categories: – biotic component and abiotic component. We shall explore what are biotic components or biotic factors.

What is Biotic Factor

Biotic factors can be defined as the living components (organisms) that shape up the environment. In other words, biotic factors comprise all living things in an ecosystem such as plants, animals and microorganisms.

Biotic factors play an important role by interacting with the environment. Animals and plants depend on each other for survival. In other cases, biotic factors, such as introduction of an invasive species may damage the balance of an ecosystem.

Biotic Factors Examples

Examples of biotic factors in various ecosystems are as follows:

  • Marine Ecosystems
    • Algae
    • Plankton
    • Bacteria
    • Plants
    • Corals
    • FIsh
    • Sharks
    • Jellyfish
  • Terrestrial Ecosystems
    • Soil bacteria
    • Fungi
    • Mushrooms
    • Trees
    • Herbs
    • Shrubs
    • Every Animal

In conclusion, biotic factors in an ecosystem comprise all living organisms. These organisms interact with each other and the abiotic factors in an ecosystem.
