Biotic And Abiotic

Biotic and abiotic are the two essential factors responsible for shaping the ecosystem. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemical agents (different gases and mineral nutrients present in the air, water, soil, etc.) in an ecosystem. Therefore, both the abiotic and biotic resources affect survival and reproduction process.

Furthermore, both these components are reliant on each other. Suppose if one of the factors is removed or altered, its repercussions will be faced by the entire ecosystem. Without a doubt, abiotic factors directly affect the survival of organisms. Read on to explore what role do abiotic and biotic resources play in the ecosystem.

Biotic and Abiotic

Biotic Meaning

The term “biotic” is formed by the combination of two terms, “bio” meaning life and “ic” meaning like. Thus, the term means life-like and is related to all the living entities present in an ecosystem.

Biotic Factors

Biotic factors relate to all the living things in the ecosystem. Their presence and their biological by-products affect the composition of an ecosystem. Biotic factors refer to all living organisms from animals and humans, to plants, fungi, and bacteria. The interactions between various biotic factors are necessary for the reproduction of each species and to fulfil essential requirements like food, etc.

Examples of Biotic Factors

Examples of biotic resources include all the living components present in an ecosystem. These include producers, consumers, decomposers and detritivores.

Abiotic Meaning

The term abiotic refers to all the non-living factors present in an ecosystem. Sunlight, water, land, all constitute the abiotic factors.

Abiotic Factors

Abiotic factors refer to all the non-living, i.e. chemical and physical factors present in the atmosphere, hydrosphere, and lithosphere. Sunlight, air, precipitation, minerals, and soil are some examples of abiotic factors. These factors have a significant impact on the survival and reproduction of species in an ecosystem.

For instance, without an adequate amount of sunlight, autotrophic organisms may not be able to survive. When these organisms eventually die, it will create a shortage of food for primary consumers. This effect cascades up the food chain, affecting every organism. Consequently, it leads to an imbalance in the ecosystem.

Examples of Abiotic Factors

Abiotic examples typically depend on the type of ecosystem. For instance, abiotic components in a terrestrial ecosystem include air, weather, water, temperature, humidity, altitude, the pH level of soil, type of soil and more. Abiotic examples in an aquatic ecosystem include water salinity, oxygen levels, pH levels, water flow rate, water depth and temperature.

Now, let’s have a look at the significant difference between the abiotic and biotic factors.

Difference between Abiotic and Biotic Resources

Following are the important difference between abiotic and biotic factors:

Difference Between Biotic Resources and Abiotic Resources

Biotic ResourcesAbiotic Resources


Biotic factors include all the living components present in an ecosystemAbiotic factors refer to all the non-living, i.e. physical conditions and chemical factors that influence an ecosystem


Examples of biotic resources include all flora and faunaExamples of abiotic factors include sunlight, water, air, humidity, pH, temperature, salinity,  precipitation, altitude, type of soil, minerals, wind, dissolved oxygen, mineral nutrients present in the soil, air and water, etc.


Biotic factors depend on abiotic factors for survival and reproductionAbiotic factors are completely independent of biotic factors


Biotic components originate from the biosphereAbiotic components originate from the lithosphere, hydrosphere and atmosphere

Frequently Asked Questions

1. What are biotic factors?

Biotic factors are the living components present in an ecosystem. More specifically, it includes all flora and fauna.

2. State a few examples of biotic resources.

  • Plants
  • Animals
  • Fungi
  • Bacteria

3. What are abiotic factors?

Abiotic factors refer to all the non-living components present in an ecosystem. It typically comprises physical and chemical components.

4. State a few examples of abiotic factors.

Abiotic factors comprise the following:

  • Climate
  • Humidity
  • Precipitation
  • Wind
  • Altitude
  • Type of soil
  • Light penetration
  • Water depth
  • Oxygen content
  • Turbidity

5. Elaborate an example of the interaction between abiotic and biotic resources.

Biotic resources include every lifeform in an ecosystem. These lifeforms rely on abiotic factors as they directly affect their growth, survival and reproduction. For instance, turbidity is an abiotic factor that majorly affects the aquatic ecosystem. High levels of turbidity inhibit the growth of submerged plants. This consequently affects other species which depend upon these plants for food or shelter.
