For example, earthworms affect the soil, which is an abiotic component if you don't include the microorganisms living in the soil. Biotic factors are dependent on abiotic factors. Light and heat energy from the sun are the main key components that biota depend on. As heat and light energy are used to form biotic components, entropy increases due to the one directional flow of energy. What is the difference between biotic and abiotic factors? Kate M. Sep 30, Biotic factors are living whereas abiotic factors are non-living.
Explanation: Abiotic factors refer to non-living factors such as water and air. It includes all living things, their interactions and all non living things in the environment. It is the foundation for the energy flow and biogeochemical cycles. Every organism in the ecosystem has its own niche and a role to play for the existence of the ecosystem. Ecosystem has two major components named biotic component and abiotic component. They are also called biotic factor and abiotic factor.
Biotic factor of the ecosystem includes all living organisms while abiotic factor includes all non living things in the ecosystem.
This is the key difference between biotic and abiotic factors. Overview and Key Difference 2. What are Biotic Factors 3. What are Abiotic Factors 4. The word biotic refers to the living organism. Hence, the biotic factors of an ecosystem refer to all living organisms in the ecosystem.
It includes plants, animals , birds , fungi, bacteria, protozoa , etc. All these organisms work together in an ecosystem. These living organisms largely depend on the abiotic factors of the ecosystem. The small biotic unit of an ecosystem is species. The success or the failure of a species depends on the adaptations of that species, competition and the resources available in the ecosystem. Different species in the community interact with each other for the resources in the environment.
When the resources are limited, only the competent species will remain in the environment, and they will be selected by natural selection. This process returns the basic components of the organisms to the soil, allowing them to be reused within that ecosystem.
