Biotic And Abiotic

Biotic and Abiotic are the twso important factors of Ecosystem which have important characters in shaping the ecosystem. The biotic factors are the living components of an ecosystem and the abiotic factors are non-living chemical and other physical components in the ecosystem. Therefore, both the Biotic and Abiotic factors affect for survival and reproduction.

Both components are related to each other, if one component or a factor is removed or changed will affect the whole ecosystem. Among both factors, Abiotic is directly affecting the survival of organisms.

Biotic and Abiotic

Biotic Factors

Biotic factors or components are mainly referred to all the living things in the ecosystem. Their presence or their materials affect the composition of an ecosystem. These materials include organisms, interactions, parts, wastes and also their presence. Factors like disease, predation, and parasitism can also be considered as biotic. All these interactions will make the difference in survival and reproduction of each species.

Abiotic Factors

Abiotic factors or components are mainly referred to all the non-living things with chemical and physical factors. It affects the ability of an organism for reproduction and survival. These can be acquired from the atmosphere, hydrosphere, and lithosphere. Sunlight, air, moisture minerals, and soil are some examples of abiotic factors. These factors have the significant impact on the survival and reproduction of species in an ecosystem. For instance, without the worthy amount of sunlight some plants are not able to survive and eventually dies, then there will be less food for plant-eating animals and this will leads to the disbalance of the ecosystem.

Now let’s have a look at the major differences between the Biotic and Abiotic.

Difference between Biotic and Abiotic.



Biotic is referred to all living parts of an ecosystem.

Abiotic is referred to all nonliving parts of an ecosystem.

Biotic factors depend on abiotic factors to survive for their survival.

Abiotic factors don’t rely on the biotic factors for their survival.

Directly or indirectly affect the individual species, community, biosphere, the population of species and ecosystem.

Affect the survival of individual species, community, biosphere, the population of species and ecosystem.

Obtained directly from the biosphere and are capable of reproduction.

Obtained directly from the lithosphere, atmosphere, and hydrosphere.

The measurement is often subjective.

The measurement is often objective.

Involved in determining the total number of living things, directly or indirectly affecting the organisms in the environment.

Involved in determining the total number and different types and of organisms existing in the environment.

Have an ability to adapt to changes in the environment.

Unable to adapt to changes in the environment.

Resources include forests, animals, plants, fungi, bacteria and more.

Resources include land, fossil fuels, water and more.

Renewable resource of energy.

Non-renewable resource of energy.

Few examples of biotic factors are all living things including, animals, plants, fungi, bacteria, etc.

Few examples of abiotic factors are sunlight, air, climate, temperature, moisture minerals, soil and more.
